Error Estimates and Analysis Results for Signorini’s Problem in Thermo-Electro-Viscoelasticity
We consider a mathematical model describing the quasi-static process of contact between a thermo-electroviscoelastic body and a rigid foundation. The contact is described by Signorini’s conditions. The variational formulation leads to a coupled system for the displacement filed, the electric potential ...
Duality Between Differentiability and Minimization in Banach Spaces
In this paper we will establish a new relationship between differentiability and optimization of convex functions. We consider convex lower semi continuous functions in Banach spaces and we characterize respectively the relation between Fr´echet (Gaˆteaux) differentiability and *strong minimum ...
Regularized Minimization of Convex Functions in Radon Nikodym Space
Convex non linear optimization problems may not have a solution in in nite dimension spaces. The aim of this paper is to formulate some new results in this topic by using "technical regularization" of the objective function. The rst result shows that a non linear convex proper lower semi-continuous ...
Some Properties of Pp-Compact Spaces
In this paper, the concepts of Pp-compact spaces by using nets, filter base and Pp-complete accumulation points are introduced and studied.
On strong CNZ rings and their extensions
T.K. Kwak and Y. Lee called a ring R satisfy the commutativity of nilpotent elements at zero[1] if ab = 0 for a, b ∈ N(R) implies ba = 0. For simplicity, a ring R is called CNZ if it satisfies the commutativity of nilpotent elements at zero. In this paper we study an extension of a CNZ ring with ...
