In this combined course we will introduce some of the most important notions for discrete groups, such as e.g. amenability, Kazhdan's property (T), residual finiteness and sofic approximations, as well as related properties of their probability measure preserving actions. The aim of the lecture is to lay the foundations for these topics and present some recent research advances. The seminar, in which students will give the talks, will focus on additional topics accompanying the lecture.
