First we study the spherical mean L^2-multiplier operators on [0,+8[xR^n. Next, we give for these operators Calderon's reproducing formulas and best approximation formulas.

This paper deals with everywhere surjections, i.e. functions defined on a topological space whose restrictions to any non-empty open subset are surjective. We introduce and discuss several constructions in different contexts; some constructions are easy, ... see more

Two problems of the general theory of relativity and a problem in the electrical heating of conductors (the so-called thermistor problem), lead to the same set of partial differential equations. This permits a unified treatment of these different problems... see more

In this paper, based on the regularization of non necessarily semicontinuous set-valued mapsestablished in [4], we prove existence results of strong approximate solutions to quasivariational inequalities,(QVI), without any continuity condition on its rela... see more

Let R be an associative ring with identity and Spec^{s}(M) denote the set of all second submodules of a right R-module M. In this paper, we present a number of new results for the second classical Zariski topology on Spec^{s}(M) for a right R-module M. We... see more

We study an example of complete intersection Calabi-Yau threefold due to Libgober and Teitelbaum, and verify mirror symmetry at a cohomological level. Direct computations allow us to propose an analogue to the Berglund-H\"ubsch mirror symmetry setup for t... see more
