报告摘要：The short course is devoted to some aspects of the theory of branching processes. We will split it into five lectures.

Lecture1:Extinction of populations: from dynasties to North Atlantic whales. Historical introduction. Extinction of families (theories of Lamark and Darwin), epidemic models, problems of vaccination, mitochondrial DNA. Galton-Watson processes: classification, basic limit theorems. Theoretical models of PCR.

Lecture2:Reduced processes. The distance to the most recent ancestor. Continuous time Markov branching processes: classification.

Lecture3:Branching processes counted by random characteristics. Queueing systems as branching processes.

Lecture4:Multitype branching processes: classification, basic limit theorems. Composition of populations. Polling queueing systems as branching processes. Decomposable branching processes. Island models.

Lecture5:Branching processes in random environment.
