## Phasenübergänge am Ising-Modell. (Phase transitions in Ising model).(German)Zbl 0612.60096

The author gives a clearly written and easily readable survey of the classical results of the Ising model. The Onsager formula, the Yang-Lee theorem, Peierls argument as well as the theory of Gibbs measures, as introduced by Dobrushin, Lanford and Ruelle are discussed.
I only miss an outlook to the more recent results (e.g. Ising models with random potentials) and the corresponding references.
