This page hosts information on Oliver Sander's talk "What is … Multigrid?" at the "What is …?" seminar. The talk will take place on Friday, January 29, 5pm at the BMS Lounge at TU MA 212. This talk will be followed by a movie with pizza and drinks.
All known solvers for elliptic finite element problems get slower with increasing problem size. All solvers? No! Linear multigrid can solve even large problems in optimal time. This makes it the method of choice for many challenging application problems.
