Lower semicontinuity of pullback attractors for a singularly nonautonomous plate equation

Electronic Journal of Differential Equations, 2012
We show the lower semicontinuity of the family of pullback attractors for the singularly nonautonomous plate equation with structural damping $$ u_{tt} + a(t,x)u_{t} + (- Delta) u_{t} + (-Delta)^{2} u + lambda u = f(u), $$ in the energy space $H^2_0(

Saddle point theorems on generalized convex spaces

Journal of Inequalities and Applications, 2000
A sharpened extension of Komiya's saddle point theorem is obtained for generalized convex spaces. Moreover, we show that convexity of the involved sets in his theorem can be replaced by acyclicity, and continuity of the involved functions by lower and ...

Well-posedness for parametric strong vector quasi-equilibrium problems with applications

Fixed Point Theory and Applications, 2011
In this article, we generalize the concept of well-posedness to the parametric strong vector quasi-equilibrium problem. Under some suitable conditions, we establish some characterizations of well-posedness for parametric strong vector quasi-equilibrium ...

Connectedness and Contractibility of Solutions in Set Optimization Under Set Less Order Relations

Journal of Mathematics
This study establishes the topological properties of solution sets in set optimization, focusing on their connectedness and contractibility. Utilizing the arcwise convexity and lower semicontinuity characteristics derived from scalarization techniques ...

A Quasistatic unilateral contact problem with slip-dependent coefficient of friction for nonlinear elastic materials

Electronic Journal of Differential Equations, 2006
Existence of a weak solution under a smallness assumption of the coefficient of friction for the problem of quasistatic frictional contact between a nonlinear elastic body and a rigid foundation is established.

On quasistability of a vector combinatorial problem with \Sigma-MINMAX and \Sigma-MINMIN partial criteria [PDF]

Computer Science Journal of Moldova, 2004
We consider one type of stability (quasistability) of a vector combinatorial problem of finding the Pareto set. Under quasistability we understand a discrete analogue of lower semicontinuity by Hausdorff of the many-valued mapping, which defines the ...
