Eric Barnes
Eric Stephen Barnes (born January 16, 1924 in Cardiff , † October 16, 2000 ) was a Welsh-Australian mathematician who dealt with number theory ( geometry of numbers , square shapes and lattice ).
Barnes emigrated to Sydney with his family in 1927. He studied French and mathematics at the University of Sydney from 1940 to 1943 , worked for the Australian military as a cryptanalyst during the war (receiving the lieutenant's license for solving a Japanese code that had withstood the efforts of the cryptologists at Bletchley Park ) and studied at Cambridge University from 1947 , where he received his doctorate under Louis Mordell in 1952 ( Minimal problems for quadratic and bilinear forms ). He also received the Smith Prize in Cambridge. He was from the 1950s at the University of Sydney and from 1959 professor at theUniversity of Adelaide , where he was a colleague of Renfrey Potts (Barnes represented pure mathematics, Potts applied). In 1983 he retired due to health problems.
The Barnes-Wall lattice is named after him and GE Wall (it exists in dimensions that are powers of 2).
In 1954 he became a Fellow of the Australian Academy of Science and received its Thomas Rankin Lyle Medal in 1959. In 1959 he was founding president of the Mathematical Association of South Australia.
