Preface... then, prudence cannot be science. Nor can it be skill. It is not science because the
matters of conduct may vary; and it is not skill because the genus of action is different from …

We investigate regular elliptic boundary-value problems in bounded domains and show the
Fredholm property for the related operators in an extended scale formed by inner product …

In generalized inner product Sobolev spaces we investigate elliptic differential problems
with additional unknown functions or distributions in boundary conditions. These spaces are …

In this paper, we find conditions under which distribution functions of randomly stopped
minimum, maximum, minimum of sums and maximum of sums belong to the class of …

We study the most general class of eigenfunction expansions for abstract normal operators
with pure point spectrum in a complex Hilbert space. We find sufficient conditions for such …

This paper is devoted to the strong law for randomly weighted sums random variables. First,
based on the properties of slowly varying functions and the de Bruijn conjugates, we prove a …

Studying the behaviour of Markov processes at boundary points of the state space has a
long history, dating back all the way to William Feller. With different motivations in mind …
