• Stabilization of solutions to nonlinear parabolic equations of the p-Laplace type
• Abstract: Abstract In the first part of the paper, we study the stabilization of solutions to nonlinear parabolic equations of the p-Laplace type in L 2(ℝ n ) for 2n/(n + 2) < p ⩽ n. The proof is based on estimates uniform in time in L 2(ℝ n , x s ) for p < n. For p = n, a similar estimate holds with x s replaced by (ln(2+ x )) s . In the second part of the paper, we prove a uniform stabilization criterion for bounded solutions. This criterion generalizes a widely known result independently proved by Zhikov and Kamin in 1976 for linear parabolic equations.

• Two-dimensional wave equation with degeneration on the curvilinear boundary of the domain and asymptotic solutions with localized initial data
• Abstract: Abstract In a two-dimensional domain Ω ⊂ R 2, we consider the wave equation with variable velocity c(x 1, x 2) degenerating on the boundary Γ = ∂Ω as the square root of the distance to the boundary, and construct an asymptotic solution of the Cauchy problem with localized initial data. This problem is related to the so-called “run-up problem” in tsunami wave theory. One main idea (also used by the authors in earlier papers in the one-dimensional case and the two-dimensional case with c 2(x 1, x 2) = x 1) is that the (singular) curve Γ is a caustic of special type. We use this idea to introduce a generalization of the Maslov canonical operator covering the problem with degeneration and obtain efficient formulas for the asymptotic solutions.

• On boundary integral operators for diffraction problems on graphs with finitely many exits at infinity
• Abstract: Abstract We consider a diffraction problem in a multi-connected domain ℝ2 \ Γ, where Γ is an oriented graph with finitely many edges some of which are infinite. The problem is described by the Helmholtz equation (1) $\mathcal{H}u(x) = \rho (x)\nabla \cdot \rho ^{ - 1} (x)\nabla u(x) + k^2 (x)u(x) = 0,x \in \mathbb{R}^2 \backslash \Gamma ,$ where ρ and k are functions bounded together with all derivatives, and by the transmission conditions (2) $u_ + (t) - u_ - (t) = 0,t \in \Gamma \backslash \mathcal{V},$ (3) $a_ + (t)(\partial u/\partial n_t )_ + (t) - a_ - (t)(\partial u/\partial n_t )_ - (t) + a_0 (t)u(t) = f(t),t \in \Gamma \backslash \mathcal{V},$ where V is the set of vertices, a ± and a 0 are functions bounded on Γ, slowly oscillating discontinuous at the vertices in V, and slowly oscillating at infinity, and f ∈ L 2(Γ). Using Green’s function for the Helmholtz operator H, we introduce simple- and double-layer potentials and reduce the diffraction problem (1)–(3) to a boundary integral equation. The main objective of the paper is to study the essential spectrum, the Fredholm property, and the index of boundary operators on Γ associated with the problem (1)–(3).

• Gauge equivalence and the inverse spectral problem for the magnetic Schrödinger operator on the torus
• Abstract: Abstract We study the inverse spectral problem for the Schrödinger operator H on the two-dimensional torus with even magnetic field B(x) and even electric potential V(x). Guillemin [11] proved that the spectrum of H determines B(x) and V(x). A simple proof of Guillemin’s results was given by the authors in [3]. In the present paper, we consider gauge equivalent classes of magnetic potentials and give conditions which imply that the gauge equivalence class and the spectrum of H determine the magnetic field and the electric potential. We also show that, generically, the spectrum and the magnetic field determine the “extended” gauge equivalence class of the magnetic potential. The proof is a modification of that in [3] with some corrections and clarifications.

• Parastatistics and phase transition from a cluster as a fluctuation to a cluster as a distinguishable object
• Abstract: Abstract A phase transition of the first kind is a jump of a function, a phase transition of the second kind is a jump of its first derivative, a phase transition of the third kind, a jump of the second derivative. A phase transition from one statistic to another is very gradual, but finally it is as considerable as the phase transition of the first kind. However, we cannot introduce a clearly defined parameter to which this transition corresponds. This is due to the fact that the fluctuations near the critical point are huge, and this violates, in the vicinity of that point, the main law of equilibrium thermodynamics, which asserts that fluctuations are relatively small. The paper describes the transition in the supercritical fluid region of equilibrium thermodynamics from parastatistics to mixed statistics, in which the Boltzmann statistics is realized for long-living clusters. In economics this corresponds to a negative nominal credit rate. Examples of this non-standard situation are presented.

• On smoothness of solutions of some elliptic functional-differential equations with degeneration
• Abstract: Abstract We consider second-order differential-difference equations in bounded domains in the case where several degenerate difference operators enter the equation. The degeneration leads to the fact that the multiplicity of the zero eigenvalue for the corresponding differential-difference operator becomes infinite. Regularity of generalized solutions for such equations is known to fail in the interior of the domain. However, we prove that the projections of solutions onto the orthogonal complement to the kernel of the “leading” difference operator remain regular in certain subdomains which form a decomposition of the original domain.

• Analytic study of a potential model of tsunami with a simple source of piston type. 2. Asymptotic formula for the height of tsunami in the far field
• Abstract: Abstract A far field asymptotic formula is derived for the single integral obtained in the first part of the research and giving the height of tsunami in the framework of the hydrodynamical potential model with a special axially-symmetric source of piston type. Conditions are indicated for the variables (of the model under consideration) that can vary in wide intervals and for which the asymptotic formula is of high precision for the calculation of the wave profile and for the time history of the height of the tsunami. Using results of manyvariant computer-aided processing, we found domains of variables of the model in which the asymptotic formula has high precision for the computations of the wave profile and of time history of height not only the leading waves of tsunami but also of tailing waves.

• Lyapunov exponent of the random Schrödinger operator with short-range correlated noise potential
• Abstract: Abstract We study the influence of disorder on propagation of waves in one-dimensional structures. Transmission properties of the process governed by the Schrödinger equation with the white noise potential can be expressed through the Lyapunov exponent γ which we determine explicitly as a function of the noise intensity σ and the frequency ω. We find uniform two-parameter asymptotic expressions for γ which allow us to evaluate γ for different relations between σ and ω. The value of the Lyapunov exponent is also obtained in the case of a short-range correlated noise, which is shown to be less than its white noise counterpart.

• Differential-geometric structures associated with the Lagrangian and a nonvariational interpretation of the Euler equations and Nöther’s theorem
• Abstract: Abstract Differential-geometry structures associated with Lagrangians are studied. A relative invariant E embraced by an extension of fundamental object is constructed (in the paper, E is referred to as the Euler relative invariant) such that the equation E = 0 is an invariant representation of the Euler equation for the variational functional. For this reason, a nonvariational interpretation of the Euler equations becomes possible, because the Euler equations need not be connected with the variational problem, and one can regard the equations from the very beginning as an equation arising when equating the Euler relative invariant to zero. Local diffeomorphisms between two structures associated with Lagrangians are also discussed. The theorem concerning conditions under which the vanishing condition for the Euler relative invariant of one of these structures leads to vanishing of the Euler invariant relative of the other structure can be treated as a nonvariational interpretation of Nöther’s theorem.

• Abstract: Abstract The purpose of this paper is to study the boundedness of the wavelet integral operator on the Besov, BMO, and H 1 spaces. Furthermore, for the basic wavelet with compact support, the boundedness of the wavelet transform on the weighted Besov spaces and on the weighted BMO spaces associated with a tempered weight function is also established.

• On a q-analog of the Baskakov basis functions
• Abstract: Abstract Recently, Agrawal and Thamer suggested a new sequence of summation-integral type operators using the Baskakov basis function. We find a generating function of the q-Baskakov basis function and suggest a q-analog of the operators. We estimate moments, give a recurrence formula, and obtain some direct results. We also mention the possibility of improving the q-operators and, finally, suggest a Bézier-type variant of the operators discussed here.
