## Description

I. Theory of phase transitions and critical phenomena: real-space renormalization group, momentum-space renormalization group. Applications: percolation, Ising model, Ginzburg-Landau Hamiltonian, epsilon expansion, two-dimensional XY model. Anomalous dimensions far from equilibrium.

II. Linear response theory.

III. Stochastic processes: Brownian motion, master equation, Fokker-Planck equation..
