Colloquium
Polyhedra in geometry, physics and chemistry

Sir Michael Francis Atiyah, OM, FRS, FRSE is a British mathematician. He grew up in Sudan and Egypt but spent most of his academic life in the United Kingdom at Oxford and Cambridge, and in the United States at the
Institute for Advanced Study. He has been president of the Royal Society, master of Trinity College, Cambridge,
chancellor of the University of Leicester, and president of the
Royal Society of Edinburgh. He is currently retired, and is an honorary professor at the University of Edinburgh.

Michael Atiyah has made fundamental contributions to many areas of mathematics, but especially to topology, geometry and analysis. From  his first major contribution -- topological K-theory - to his more recent work on quantum field
theory, Atiyah has been influential in the  development of new theoretical tools and has supplied far-reaching insights. He is a notable collaborator, with his name linked with other  oustanding mathematcians through their joint research.
