Dear all, Prof Luke Olson from University of Illinois at Urbana-Champaign is a leading expert in algebraic multigrid methods, visiting the department for six months on a Nelder Fellowship. Unfortunately this was interrupted by the covid19 pandemic and he and his family have returned to Illinois. However, Luke is still able to give his scheduled course on multigrid methods in a virtual format. This will comprise 4x2 hours sessions (Luke anticipates that he won't use the whole 2 hours, probably something just over an hour per session with discussion afterwards). These will be: Wednesday 6th May 4pm (BST) Friday 8th May 4pm (BST) Monday 11th May 4pm (BST) Friday 15th May 4pm (BST) There is a sign-up sheet for the course here: https://docs.google.com/spreadsheets/d/13Z5VSijFgn3SGng9YJMfR8nRF8ATs4wpy7sg... and course materials will be uploaded to this git repository: https://github.com/lukeolson/imperial-multigrid The course will be a mixture of analysis and practical aspects. Luke is a great communicator and teacher so I hope that you will be able to join this excellent course. See you there! all the best --Colin Professor Colin Cotter (he/him) Department of Mathematics 755, Huxley Building Imperial College London South Kensington Campus United Kingdom of Great Britain and Northern Ireland +44 2075943468
