In this paper we discuss the problem of representing hyperbolic differential operators using orthonormal wavelet bases. A numerical algorithm is shortly outlined and a numerical experiment in the linear magnetohydrodynamics, ...

We study existence and regularity of solutions of noncoercive variational inequalities.

We consider evolution variational inequalities with λ₀-pseudomonotone maps. The main properties of the given maps have been investigated. By using the finite differences method, strong solvability for the class of evolution ...
