ABSTRACT

This is the third issue of the special collection dedicated to the memory of Evgeny Pechersky.

The present volume opens with a paper devoted to risk theory and queueing systems. This area of probability theory was particularly close to Evgeny Pechersky, who made significant contributions to queueing theory throughout his scientific career.

One of the topics that particularly interested Evgeny Pechersky in his last years was the possibility of using queueing models to describe phenomena arising in modern power grids. In particular, he was fascinated by the problem of modeling rare but critical events, such as cascading failures and large-scale blackouts. He was especially intrigued by the possibility of applying methods of large deviations to estimate the probabilities of such events and to identify the most vulnerable components of a network, whose failure could trigger a cascade of subsequent breakdowns.

Unfortunately, he did not have the opportunity to pursue these ideas further. Nevertheless, they reflect one of Evgeny Pechersky’s most distinctive qualities as a mathematician: his constant curiosity, his readiness to explore new directions, and his remarkable ability to recognize deep probabilistic questions arising in new applied settings.

The Guest Editors would like to express their sincere gratitude to all authors who contributed to this special collection in memory of Evgeny Pechersky. We also thank the referees for their careful evaluations and valuable comments, which have greatly helped to maintain the high scientific standards of these volumes. We are especially pleased that this issue brings together contributions from longtime collaborators and colleagues of Evgeny Pechersky, together with papers reflecting the remarkable breadth of his scientific interests.
