• Authors: annalsmath
Abstract: Received: 29.VIII.2018, Accepted: 29.XI.2018 Abstract. It is well known that the ideal membership problem for free Lie algebras is undecidable which implies the undecidability of the ideal membership problem for free Poisson algebras. Using that fact we prove that  the [...]

• Lightlike hypersurfaces of an indefinite nearly trans-Sasakian manifold

• Authors: annalsmath
Abstract: Received: 16.V.2018, Accepted: 09.X.2018 Abstract. In this paper, we study lightlike hypersurfaces M of an indefinite nearly trans-Sasakian manifold M or an indefinite nearly generalized Sasakian space form M(f1, f2, f3)  with a tangential trans-Sasakian structure vector field ζ subject such that [...]

• On split equality problem for proximal point algorithm

• Authors: annalsmath
Abstract: Received: 12.III.2018, Accepted: 16.V.2018 Abstract. In this paper, we introduce a modified Mann iterative scheme for solving a split equality proximal point algorithm problem. We also establish strong convergence of this iterative sequence to a minimizer of a convex function [...]

• Hyperholomorphy of multiplicative inverse functions of bicomplex variables

• Authors: annalsmath
Abstract: Received: 11.I.2018, Accepted: 03.V.2018 Abstract. In this paper, we give some algebraic properties of bicomplex numbers and some different forms of bicomplex conjugations, based on the expression of the usual complex conjugation. We provide the multiplicative inverse forms and hyperholomorphy [...]

• Rings with very few nilpotents

• Authors: annalsmath
Abstract: Received: 19.II.2016, Accepted: 10.I.2017 Abstract. We show that any indecomposable ring with only 3 nonzero nilpotent elements, pairwise not commuting, is isomorphic to the ring of $2\times 2$ matrices over the 2-element field. Rings with only one or two nonzero [...]

• The center map of a centroaffine ruled surface

• Authors: annalsmath
Abstract: Received: 12.VI.2017, Accepted: 21.IX.2017 Abstract. We determine a nondegenerate centroaffine ruled surface such that the image of its center map lies on a plane containing the origin. A centroaffine minimal surface such that the image of the center map lies on [...]

• Directed weak and directed Dold fibrations

• Authors: annalsmath
Abstract: Received: 4.V.2017, Accepted: 14.III.2018 Abstract. In a previous paper [21] the author studied the homotopy lifting property in the category dTop of directed spaces in the sense of M. Grandis [12], [13], [14]. The present paper, which is a continuation of [...]

• Uniqueness results related to certain q-shift difference polynomials

• Authors: annalsmath
Abstract: Received: 6.XII.2016, Revised: 7.VII.2017, Accepted: 8.III.2018 Abstract. In this paper, we investigate the uniqueness problems of certain $q$-shift difference polynomials sharing a value or a small function or a polynomial with finite weights. The results of this paper improve and [...]

• Generalized para-coKähler structures

• Authors: annalsmath
Abstract: Received: 6.I.2018, Accepted: 1.III.2018 Abstract. In this paper, we define and characterize generalized almost para-contact pseudo-metric structures. Then, we define normal generalized para-contact pseudo-metric structures and generalized para-coKähler structures and give some examples of them. Keywords: Generalized almost para-contact structure, [...]
