On the worst scenario method: a modified convergence theorem and its application to an uncertain differential equation

Petr Harasim (2008)

Applications of Mathematics

Similarity:

We propose a theoretical framework for solving a class of worst scenario problems. The existence of the worst scenario is proved through the convergence of a sequence of approximate worst scenarios. The main convergence theorem modifies and corrects the relevant results already published in literature. The theoretical framework is applied to a particular problem with an uncertain boundary value problem for a nonlinear ordinary differential equation with an uncertain coefficient. ...

Boundedness and pointwise differentiability of weak solutions to quasi-linear elliptic differential equations and variational inequalities

Jana Ježková (1994)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

The local boundedness of weak solutions to variational inequalities (obstacle problem) with the linear growth condition is obtained. Consequently, an analogue of a theorem by Reshetnyak about a.eḋifferentiability of weak solutions to elliptic divergence type differential equations is proved for variational inequalities.

Similarity:

The aim of this article is to give a regularization method for an unilateral obstacle problem with obstacle ψ and second member f , which generalizes the one established by the authors of [4] in case of null obstacle and a second member is equal to constant 1 .
