Ruelle David

David Ruelle (David Pierre Ruelle) — born 20 August 1935 in Destelbergen, Belgium — is a renowned theoretical physicist and mathematician whose work helped shape the modern study of statistical mechanics and dynamical systems. He is best known for introducing the thermodynamic formalism and for the development of the Ruelle operator, central tools in the analysis of chaotic systems.
