Walter Hayman

Walter Kurt Hayman FRS (6 January 1926 – 1 January 2020) was a British mathematician known for contributions to complex analysis.^[1] He was a professor at Imperial College London.^[2]

Life and work

In 1947, he married Margaret Riley Crann: together, they founded the British Mathematical Olympiad.^[6]

He is known for his asymptotic results in

Hayman was elected to the Royal Society in 1956 and of the Finnish Academy of Science and Letters in 1978:^[8] he was elected "Foreign member" of the Accademia dei Lincei on 16 December 1985.^[9] In 1992 he received an honorary doctorate from the Faculty of Mathematics and Science at Uppsala University, Sweden^[10] In 1995 he was awarded the De Morgan Medal by the London Mathematical Society.^[11] In 2008, an issue of the Journal Computational Methods and Function Theory was dedicated to him on the occasion of his 80th birthday.^[12]
