from Wikipedia, the free encyclopedia

William Parry (born July 3, 1934 in Coventry , † August 20, 2006 in Marton , Warwickshire ) was a British mathematician who dealt with dynamic systems and ergodic theory .

Parry came from a family of steel workers and he retained socialist beliefs throughout his life (he was also a member of the Communist Party until the Hungarian uprising). He studied at University College London , the University of Liverpool (Masters degree) and at Imperial College London, where he received his doctorate in 1960 with Yael Dowker . He was a lecturer at the University of Birmingham (1960 to 1965) and the University of Sussex and became a reader at the newly founded University of Warwick in 1968 and professor in 1970. 1984–1986 he headed the mathematics faculty. He died of cancer.

The Parry-Daniels mapping , the Parry-Sullivan invariant and the Parry measure are named after him in the theory of dynamic systems.

In 1970 he was invited speaker at the International Congress of Mathematicians in Nice (Ergodic theory of G-spaces). In 1984 he became a Fellow of the Royal Society .

His PhD students include Mary Rees and Mark Pollicott .

He was married and had a daughter.
