Stability of functional equations in dislocated quasi-metric spaces
Journal Title: Annales Mathematicae Silesianae - Year 2018, Vol 32, Issue
Abstract
We present a result on the generalized Hyers–Ulam stability of a functional equation in a single variable for functions that have values in a complete dislocated quasi-metric space. Next, we show how to apply it to prove stability of the Cauchy functional equation and the linear functional equation in two variables, also for functions taking values in a complete dislocated quasi-metric space. In this way we generalize some earlier results proved for classical complete metric spaces.

Mathematical challenges in the theory of chemotaxis
We consider the simplest parabolic-elliptic model of chemotaxisin the whole space and in several space dimensions. Criteria either for theexistence of radial global-in-time solutions or their blowup in terms of suitable...
Numerical solution of time fractional Schrödinger equation by using quadratic B-spline finite elements
In this article, quadratic B-spline Galerkin method has been employed to solve the time fractional order Schrödinger equation. Numerical solutions and error norms $L_2$ and $L_∞$ are presented in tables.
Generalizations of some integral inequalities for fractional integrals
In this paper we give generalizations of the Hadamard-type inequalities for fractional integrals. As special cases we derive several Hadamard type inequalities.
On the continuous dependence of solutions to orthogonal additivity problem on given functions
We show that the solution to the orthogonal additivity problem in real inner product spaces depends continuously on the given function and provide an application of this fact.
Universally Kuratowski–Ulam spaces and open-open games
We examine the class of spaces in which the second player has a winning strategy in the open-open game. We show that this spaces are not universally Kuratowski–Ulam. We also show that the games $G$ and $G_7$ introduced b...
