The method based upon a constructive reduction of coercive singular perturbations to regular ones, introduced in 1977 (see [4]) and developed later on (see [9–11]) is applied for computing the asymptotic expansions for eigenvalues of coercive singu

General coercive singular perturbations are reduced to regular ones, using an algebra of singularly perturbed Wiener-Hopf type operators. High order asymptotic formulae, also for non-smooth data, are indicated and sharp error estimates are establishe

In a recent paper [3] Evans and Friedman proved the existence of a global classical solution for two immiscibIe fluids in a one-dimensional porous medium; a solution in a weaker sense was earlier established by Evans [l] [2]. As for uniqueness, the o

In this paper, difference analogs of Sobolev–Slobodeckiĭ spaces are studied: , where is either the whole space or a halfspace. One obtains difference analogs of imbedding theorems, on traces and on extensions of network functions from a halfspace

An algebra of difference operators is introduced and some of their properties are studied. It is shown that this is aC*-algebra and a differences analogue of Garding’s inequality is proved.

A family of elliptic operators with discontinuous nonlinearity affected by the presence of a positive parameter λ is considered. A critical value λc of λ and the zero-set Ec of the corresponding critical solution uλc play a special role in the tr
