Claude Ambrose Rogers FRS[1] (1 November 1920 – 5 December 2005) was an English mathematician who worked in analysis and geometry.[2][3][4]

Research

Much of his work concerns the Geometry of Numbers, Hausdorff Measures, Analytic Sets, Geometry and Topology of Banach Spaces, Selection Theorems and Finite-dimensional Convex Geometry.[5][6][7][8] In the theory of Banach spaces and summability, he proved the Dvoretzky–Rogers lemma and the Dvoretzky–Rogers theorem, both with Aryeh Dvoretzky.[9][10][11][12] He constructed a counterexample to a conjecture related to the Busemann–Petty problem. In the geometry of numbers, the Rogers bound is a bound for dense packings of spheres.

Awards and honours

Rogers was elected a Fellow of the Royal Society (FRS) in 1959. He won the London Mathematical Society's De Morgan Medal in 1977.

Personal life

Rogers was married to children's writer Joan North.[4] They had two daughters, Jane and Petra.
