General equilibrium theory Lecture notes

Lecture Notes in General Equilibrium Theory

The Elements of General Equilibrium Theory

The lecture will be an introduction to the model of economic equilibrium. The basic concepts: preferences, initial endowments and market clearing prices will discussed in general and by means of examples. I will indicate how fixed point theorems are used to demonstrate the existence of equilibrium prices and sketch an algorithm for Brouwers theorem. If time permits, there will be some remarks o...

Non-equilibrium phase transitions

These lecture notes give a basic introduction to the physics of phase transitions under non-equilibrium conditions. The notes start with a general introduction to non-equilibrium statistical mechanics followed by four parts. The first one discusses the universality class of directed percolation, which plays a similar role as the Ising model in equilibrium statistical physics. The second one giv...

Non-equilibrium steady states: fluctuations and large deviations of the density and of the current

These lecture notes give a short review of methods such as the matrix ansatz, the additivity principle or the macroscopic fluctuation theory, developed recently in the theory of non-equilibrium phenomena. They show how these methods allow us to calculate the fluctuations and large deviations of the density and the current in non-equilibrium steady states of systems like exclusion processes. The...
