Abstract: We will talk about the proof of Manin's conjecture on the asymptotic density of rational points of bounded height for the special case of a compactification of a semisimple algebraic group defined over a number field. The main tool is the mixing property (or equivalently, the decay of matrix coefficients) of the quasi-regular representation of the associated Adele group. No background in algebraic geometry or adeles will be assumed. If time permits, I will also discuss a new approach to Manin's conjecture based on Ratner's theory of unipotent flows.
