About one discrete analog of Hausdorff semi-continuity of suitable mapping in a vector combinatorial problem with a parametric principle of optimality ("from Slater to lexicographic")

Journal of Numerical Analysis and Approximation Theory, 2006
multicriteria linear combinatorial problem is considered, principle of optimality of which is defined by a partitioning of partial criteria onto groups with Slater preference relation within each group and the lexicographic preference relation ...

Robust exponential attractors for singularly perturbed phase-field type equations

Electronic Journal of Differential Equations, 2002
In this article, we construct robust (i.e. lower and upper semicontinuous) exponential attractors for singularly perturbed phase-field type equations. Moreover, we obtain estimates for the symmetric distance between these exponential attractors and that ...

On the Differences of Lower Semicontinuous Functions

Real Analysis Exchange, 2016
Answering one of the real function problems suggested by A. Maliszewski, the existence of a bounded Darboux function of the Sierpinski first class which cannot be expressed as a difference of two bounded lower semicontinuous functions is proved. As the reply to the other Maliszewski question, we show there exists an almost everywhere continuous Darboux

A quasistatic bilateral contact problem with friction for nonlinear elastic materials

Electronic Journal of Differential Equations, 2006
We consider a mathematical model describing the bilateral contact between a deformable body and a foundation. We use a nonlinear elastic constitutive law. The contact takes into account the effects of friction, which are modelled with the

Structure and stability of global attractors for a Cahn-Hilliard tumor growth model with chemotaxis

Electronic Journal of Differential Equations
In this article, we analyze the long-time dynamics of a Cahn-Hilliard tumor growth model, focusing on the geometric structure and stability of its global attractors.

On a minimax problem of ricceri

Journal of Inequalities and Applications, 2001
Let be a real separable and reflexive Banach space, weakly closed and unbounded, and two non-constant weakly sequentially lower sernicontinuous functionals defined on , such that is coercive for each . In this setting, if for every , then, one has
