Walter Kurt Hayman FRS (born in Cologne, 6 January 1926) is a British mathematician known for contributions to complex analysis. He is Emeritus Professor at Imperial College London.[1]

Life

Hayman was born in Cologne, Germany, the grandson of mathematician Kurt Hensel.[2] He immigrated to Britain in 1938, studying at Gordonstoun School, and later at St John's College, Cambridge, with Mary Cartwright and John Edensor Littlewood. He taught at King's College, Newcastle, and the University of Exeter.[3]

In 1947, he married Margaret Riley Crann: together, they founded the British Mathematical Olympiad.[4]

Honours and awards

Hayman was elected to the Royal Society in 1956 and of the Finnish Academy of Science and Letters in 1978:[5] he was elected "Foreign member" of the Accademia dei Lincei on 16 December 1985.[6] In 1992 he received an honorary doctorate from the Faculty of Mathematics and Science at Uppsala University, Sweden[7] In 1995 He was awarded the De Morgan Medal by the London Mathematical Society.[8] In 2008, an issue of the Journal Computational Methods and Function Theory was dedicated to him on the occasion of his 80th birthday.[9]

Selected publications

Hayman presents a talk at the 2010 One Day Function Theory Meeting.
