Coincidence point theorems for $\varphi-\psi-$contraction mappings in metric spaces involving a graph
Journal Title: Карпатські математичні публікації - Year 2016, Vol 8, Issue 2
Abstract
Some new coupled coincidence and coupled common fixed point theorems for $\varphi-\psi-$contraction mappings are established. We have also an application to some integral system to support the results.

Topology on the spectrum of the algebra of entire symmetric functions of bounded type on the complex $L_\infty$
It is known that the so-called elementary symmetric polynomials $R_n(x) = \int_{[0,1]}(x(t))^n\,dt$ form an algebraic basis in the algebra of all symmetric continuous polynomials on the complex Banach space $L_\infty,$...
