Invertibility of matrix type operators of infinite order with exponential off-diagonal decay
Stevan Pilipovic, Bojan Prangoski, Milica Zigic
We analyse various exponential off-diagonal decay rates of the elements of infinite matrices and their inverses. It is known that such decay of the elements of an infinite matrix d…

Generalized exponentially bounded integrated semigroups
Marko Kostic, Stevan Pilipovic, Milica Zigic
The main subject of this paper is the analysis of sequences of exponentially bounded integrated semigroups which are related to Cauchy problems \begin{equation}\label{jed} \frac{\p…
