The asymptotic behaviour, in particular" stability" in some sense, is studied systematically for
discrete and for continuous linear dynamical systems on Banach spaces. Of particular …

We give an account of some results, both old and new, about any n*n Markov matrix that is
embeddable in a one-parameter Markov semigroup. These include the fact that its …

We consider the power-law uniform (in the operator norm) convergence on vector
subspaces with their own norms in the von Neumann ergodic theorem with discrete time. All …

Embedding discrete Markov chains into continuous ones is a famous open problem in
probability theory with many applications. Inspired by recent progress, we study the closely …

We study the typical behavior of bounded linear operators on infinite-dimensional complex
separable Hilbert spaces in the norm, strong-star, strong, weak polynomial and weak …

We show that the set of unitary operators on a separable infinite-dimensional Hilbert space
is residual (for the weak operator topology) in the set of all contractions. The same holds for …

We generalise a technique of Bhat and Skeide (J Funct Anal 269: 1539–1562, 2015) to
interpolate commuting families {S i} i∈ I of contractions on a Hilbert space H, to commuting …

У монографії розглянуто задачі моделювання систем та процесів з розподіленими
параметрами, характеристики яких представлено у вигляді числових інтервалів …

In this paper we study the embedding problem of an operator into a strongly continuous
semigroup. We obtain characterizations for some classes of operators, namely composition …
