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:
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
