On the superstability of generalized d’Alembert harmonic functions
The aim of this paper is to study the superstability problem of the d’Alembert type functional equation f(x + y + z) + f(x + y + σ(z)) + f(x + σ(y) + z) + f(σ(x) + y + z) = 4f(x)f(y)f(z) for all x, y, z ∈ G, where G is ...

Affine analogues of the Sasaki-Shchepetilov connection
For two-dimensional manifold M with locally symmetric connection ∇ and with ∇-parallel volume element vol one can construct a flat connection on the vector bundle TM ⊕ E, where E is a trivial bundle. The metrizable case, ...
Construction of a common element for the set of solutions of fixed point problems and generalized equilibrium problems in Hilbert spaces
In this paper, we propose and analyse an iterative algorithm for the approximation of a common solution for a finite family of k-strict pseudocontractions and two finite families of generalized equilibrium problems in the ...
An integro-differential inequality related to the smallest positive eigenvalue of p(x)-Laplacian Dirichlet problem
We consider the eigenvalue problem for the p(x)-Laplace-Beltrami operator on the unit sphere. We prove same integro-differential inequalities related to the smallest positive eigenvalue of this problem.
On the superstability of the cosine and sine type functional equations
In this paper, we study the superstablity problem of the cosine and sine type functional equations: f(xσ(y)a) + f(xya) = 2f(x)f(y) and f(xσ(y)a) − f(xya) = 2f(x)f(y), where f : S → C is a complex valued function; S is ...
Properties of two variables Toeplitz type operators
The investigation of properties of generalized Toeplitz operators with respect to the pairs of doubly commuting contractions (the abstract analogue of classical two variable Toeplitz operators) is proceeded. We ...
New method to solve certain differential equations
A new method to solve stationary one-dimensional Schroedinger equation is investigated. Solutions are described by means of representation of circles with multiple winding number. The results are demonstrated using the ...
