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 [...] PubDate: Wed, 18 Dec 2019 13:52:12 +000

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 [...] PubDate: Fri, 02 Nov 2018 07:36:49 +000

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 [...] PubDate: Fri, 02 Nov 2018 06:28:31 +000

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 [...] PubDate: Fri, 02 Nov 2018 05:38:41 +000

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 [...] PubDate: Wed, 04 Apr 2018 09:48:07 +000

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 [...] PubDate: Wed, 04 Apr 2018 07:51:00 +000

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 [...] PubDate: Mon, 26 Mar 2018 11:05:13 +000

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 [...] PubDate: Mon, 26 Mar 2018 10:41:25 +000

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, [...] PubDate: Mon, 26 Mar 2018 10:28:44 +000

Abstract: Received: 21.IX.2017, Revised: 7.II.2018, Accepted: 1.III.2018 Abstract. Shah and Debnath [Tight wavelet frames on local fields, Analysis, 33 (2013), 293-307] have derived an explicit method for constructing tight wavelet frames on local fields using the machinery of unitary extension principle.
