• Brill-Noether theory for curves of a fixed gonality

• Authors: Jensen; David, Ranganathan, Dhruv
First page: 1
Abstract: We prove a generalisation of the Brill-Noether theorem for the variety of special divisors on a general curve C of prescribed gonality. Our main theorem gives a closed formula for the dimension of. We build on previous work of Pflueger, who used an analysis of the tropical divisor theory of special chains of cycles to give upper bounds on the dimensions of Brill-Noether varieties on such curves. We prove his conjecture, that this upper bound is achieved for a general curve. Our methods introduce logarithmic stable maps as a systematic tool in Brill-Noether theory. A precise relation between the divisor theory on chains of cycles and the corresponding tropical maps theory is exploited to prove new regeneration theorems for linear series with negative Brill-Noether number. The strategy involves blending an analysis of obstruction theories for logarithmic stable maps with the geometry of Berkovich curves. To show the utility of these methods, we provide a short new derivation of lifting for special divisors on a chain of cycles with generic edge lengths, proved using different techniques by Cartwright, Jensen, and Payne. A crucial technical result is a new realisability theorem for tropical stable maps in obstructed geometries, generalising a well-known theorem of Speyer on genus curves to arbitrary genus.

• The fields of values of characters of degree not divisible by p

• Authors: Navarro; Gabriel, Tiep, Pham Huu
First page: 2
Abstract: We study the fields of values of the irreducible characters of a finite group of degree not divisible by a prime p. In the case where , we fully characterise these fields. In order to accomplish this, we generalise the main result of [ILNT] to higher irrationalities. We do the same for odd primes, except that in this case the analogous results hold modulo a simple-to-state conjecture on the character values of quasi-simple groups.

• Holomorphic anomaly equation for $({\mathbb P}^2,E)$ and the
Nekrasov-Shatashvili limit of local ${\mathbb P}^2$

• Authors: Bousseau; Pierrick, Fan, Honglu, Guo, Shuai, Wu, Longting
First page: 3
Abstract: We prove a higher genus version of the genus local-relative correspondence of van Garrel-Graber-Ruddat: for a pair with X a smooth projective variety and D a nef smooth divisor, maximal contact Gromov-Witten theory of with -insertion is related to Gromov-Witten theory of the total space of and local Gromov-Witten theory of D.Specializing to for S a del Pezzo surface or a rational elliptic surface and E a smooth anticanonical divisor, we show that maximal contact Gromov-Witten theory of is determined by the Gromov-Witten theory of the Calabi-Yau 3-fold and the stationary Gromov-Witten theory of the elliptic curve E.Specializing further to , we prove that higher genus generating series of maximal contact Gromov-Witten invariants of are quasimodular and satisfy a holomorphic anomaly equation. The proof combines the quasimodularity results and the holomorphic anomaly equations previously known for local and the elliptic curve.Furthermore, using the connection between maximal contact Gromov-Witten invariants of

• Simultaneously vanishing higher derived limits

• Authors: Bergfalk; Jeffrey, Lambie-Hanson, Chris
First page: 4
Abstract: In 1988, Sibe Mardešić and Andrei Prasolov isolated an inverse system with the property that the additivity of strong homology on any class of spaces which includes the closed subsets of Euclidean space would entail that (the nth derived limit of ) vanishes for every . Since that time, the question of whether it is consistent with the axioms that for every has remained open. It remains possible as well that this condition in fact implies that strong homology is additive on the category of metric spaces.We show that assuming the existence of a weakly compact cardinal, it is indeed consistent with the axioms that for all . We show this via a finite-support iteration of Hechler forcings which is of weakly compact length. More precisely, we show that in any forcing extension by this iteration, a condition equivalent to will hold for each . This condition is of interest in its own right; namely, it is the triviality of every coherent

• Frobenius splitting of Schubert varieties of semi-infinite flag manifolds

• Authors: Kato; Syu
First page: 5
Abstract: We exhibit basic algebro-geometric results on the formal model of semi-infinite flag varieties and its Schubert varieties over an algebraically closed field of characteristic from scratch. We show that the formal model of a semi-infinite flag variety admits a unique nice (ind-)scheme structure, its projective coordinate ring has a -model and it admits a Frobenius splitting compatible with the boundaries and opposite cells in positive characteristic. This establishes the normality of the Schubert varieties of the quasi-map space with a fixed degree (instead of their limits proved in [K, Math. Ann. 371 no.2 (2018)]) when or , and the higher-cohomology vanishing of their nef line bundles in arbitrary characteristic . Some particular cases of these results play crucial roles in our proof [47] of a conjecture by Lam, Li, Mihalcea and Shimozono [60] that describes an isomorphism between affine and quantum K-groups of a flag manifold.

• On the derivation of the wave kinetic equation for NLS

• Authors: Deng; Yu, Hani, Zaher
First page: 6
Abstract: A fundamental question in wave turbulence theory is to understand how the wave kinetic equation describes the long-time dynamics of its associated nonlinear dispersive equation. Formal derivations in the physics literature, dating back to the work of Peierls in 1928, suggest that such a kinetic description should hold (for well-prepared random data) at a large kinetic time scale and in a limiting regime where the size L of the domain goes to infinity and the strength of the nonlinearity goes to (weak nonlinearity). For the cubic nonlinear Schrödinger equation, and is related to the conserved mass of the solution via .In this paper, we study the rigorous justification of this monumental statement and show that the answer seems to depend on the particular scaling law in which the limit is taken, in a spirit similar to how the Boltzmann–Grad scaling law is imposed in the derivation of Boltzmann’s equation. In particular, there appear to be two favourable scaling laws: when approaches like or like

• Smoothing toroidal crossing spaces

• Authors: Felten; Simon, Filip, Matej, Ruddat, Helge
First page: 7
Abstract: We prove the existence of a smoothing for a toroidal crossing space under mild assumptions. By linking log structures with infinitesimal deformations, the result receives a very compact form for normal crossing spaces. The main approach is to study log structures that are incoherent on a subspace of codimension 2 and prove a Hodge–de Rham degeneration theorem for such log spaces that also settles a conjecture by Danilov. We show that the homotopy equivalence between Maurer–Cartan solutions and deformations combined with Batalin–Vilkovisky theory can be used to obtain smoothings. The construction of new Calabi–Yau and Fano manifolds as well as Frobenius manifold structures on moduli spaces provides potential applications.

• Endoscopic decompositions and the Hausel–Thaddeus conjecture

• Authors: Maulik; Davesh, Shen, Junliang
First page: 8
Abstract: We construct natural operators connecting the cohomology of the moduli spaces of stable Higgs bundles with different ranks and genera which, after numerical specialisation, recover the topological mirror symmetry conjecture of Hausel and Thaddeus concerning - and -Higgs bundles. This provides a complete description of the cohomology of the moduli space of stable -Higgs bundles in terms of the tautological classes, and gives a new proof of the Hausel–Thaddeus conjecture, which was also proven recently by Gröchenig, Wyss and Ziegler via p-adic integration.Our method is to relate the decomposition theorem for the Hitchin fibration, using vanishing cycle functors, to the decomposition theorem for the twisted Hitchin fibration, whose supports are simpler.

• Inverse problems for nonlinear hyperbolic equations with disjoint sources

• Authors: Feizmohammadi; Ali, Lassas, Matti, Oksanen, Lauri
First page: 10
Abstract: The article studies inverse problems of determining unknown coefficients in various semi-linear and quasi-linear wave equations given the knowledge of an associated source-to-solution map. We introduce a method to solve inverse problems for nonlinear equations using interaction of three waves that makes it possible to study the inverse problem in all globally hyperbolic spacetimes of the dimension and with partial data. We consider the case when the set , where the sources are supported, and the set , where the observations are made, are separated. As model problems we study both a quasi-linear equation and a semi-linear wave equation and show in each case that it is possible to uniquely recover the background metric up to the natural obstructions for uniqueness that is governed by finite speed of propagation for the wave equation and a gauge corresponding to change of coordinates. The proof consists of two independent components. In the geometric part of the article we introduce a novel geometrical object, the three-to-one scattering relation. We show that this relation determines uniquely the topological, differential and conformal structures of the Lorentzian manifold in a causal diamond set that is the intersection of the future of the point and the past of the point . In the analytic part of the article we study multiple-fold linearisation of the nonlinear wave equation using Gaussian beams. We show that the source-to-solution map, corresponding to sources in and observations in , determines the three-to-one scattering relation. The methods developed in the article do not require any assumptions on the conjugate or cut points.

• Equitable colourings of Borel graphs

• Authors: Bernshteyn; Anton, Conley, Clinton T.
First page: 12
Abstract: Hajnal and Szemerédi proved that if G is a finite graph with maximum degree , then for every integer , G has a proper colouring with k colours in which every two colour classes differ in size at most by ; such colourings are called equitable. We obtain an analogue of this result for infinite graphs in the Borel setting. Specifically, we show that if G is an aperiodic Borel graph of finite maximum degree , then for each , G has a Borel proper k-colouring in which every two colour classes are related by an element of the Borel full semigroup of G. In particular, such colourings are equitable with respect to every G-invariant probability measure. We also establish a measurable version of a result of Kostochka and Nakprasit on equitable -colourings of graphs with small average degree. Namely, we prove that if , G does not contain a clique on vertices and is an atomless G-invariant probability measure such that the average degree of G with respect to is at most , then G has a
