Boundary value problems for a second-order elliptic equation in unbounded domains
(2010)We investigate the behaviour of weak solutions to the boundary value problems for the second order elliptic linear equation in a neighborhood of innity. The exponent of the decreasing rate of solutions at innity has been ... -
On asymptotic cyclic contractions
(2010)We introduce asymptotic cyclic contractions as a generalization of cyclic contractions and this new type of mappings is considered under the recently introduced property UC for pairs of subsets of metric spaces. We show ... -
On Schwarz-type boundary-value problems of polyanalytic equation on a triangle
(2010)We will consider the Schwarz-type boundary-value problems (BVPs) of the polyanalytic equation on an isosceles orthogonal triangle. In contrast to [1], the expression of its unique solution are explicitly obtained by the ... -
On the hat problem, its variations, and their applications
(2010)The topic of our paper is the hat problem in which each of n players is randomly fitted with a blue or red hat. Then everybody can try to guess simultaneously his own hat color by looking at the hat colors of the other ... -
On a generalization of the Popoviciu equation on groups
(2010)We determine a general solution of the Popoviciu type functional equation on groups. -
Unstable (Stable) system of stable (unstable) functional equations
(2010)In this note the answer to a question by Z. Moszner from the paper [1] about connections of stability of separate equations and the system of them, is given. -
Global aspects of the geometry of surfaces
(2010)Several open problems related to the behavior of the monoid of effective divisors and the nef cone for smooth projective surfaces over an algebraically closed field are discussed, motivating and putting into historical ... -

Translation equation and the Jordan non-measurable continuous functions
(2017)A connection between the continuous translation equation and the Jordan non-measurable continuous functions is given. -
Like $N’s$ – a point of view on natural numbers
(2017)We define and study some simple structures which we call likens and which are conceptually near to both sets of natural numbers, i.e. $N$ with addition and $N^* = N$ \ $\{0\}$ with multiplication. It appears that there are ... -
On type-2 m-topological spaces
(2017)In the present paper, we define a notion of an m2-topological space by introducing a count of openness of a multiset (mset in short) and study the properties of m2-subspaces, mgp-maps etc. Decomposition theorems involving ... -
Intersect a quartic to extract its roots
(2017)In this note we present a new method for determining the roots of a quartic polynomial, wherein the curve of the given quartic polynomial is intersected by the curve of a quadratic polynomial (which has two unknown co ... -
Some results on pseudo-Q algebras
(2017)The notions of a dual pseudo-Q algebra and a dual pseudo-QC algebra are introduced. The properties and characterizations of them are investigated. Conditions for a dual pseudo-Q algebra to be a dual pseudo-QC algebra ... -
Strong sequences and partition relations
(2017)The first result in partition relations topic belongs to Ramsey (1930). Since that this topic has been still explored. Probably the most famous partition theorem is Erdös-Rado theorem (1956). On the other hand in 60’s ... -
Local convergence of a multi-step high order method with divided differences under hypotheses on the first derivative
(2017)This paper is devoted to the study of a multi-step method with divided differences for solving nonlinear equations in Banach spaces. In earlier studies, hypotheses on the Fréchet derivative up to the sixth order of the ... -
Discrete-time market models from the small investor point of view and the first fundamental-type theorem
(2017)In this paper, we discuss the no-arbitrage condition in a discrete financial market model which does not hold the same interest rate assumptions. Our research was based on, essentially, one of the most important results ... -
Fekete-Szegö inequalities associated with k[th] root transformation based on quasi-subordination
(2017)Recently, Haji Mohd and Darus [1] revived the study of coefficient problems for univalent functions associated with quasi-subordination. Inspired largely by this article, we provide coefficient estimates with k-th ... -
