Algebra seminar in Lincoln: talk by Dr Lukasz Grabowski

On Wednesday the 31st of January 2018 Dr Lukasz Grabowski (Lancaster University) visited Lincoln and gave a talk “Quotients of groups by torsion elements”.

Abstract: Our recent result with Gabor Elek deals with the variant of the “Halmos problem” for the rank metric. A particular case is as follows: if A and B are either unitary or self-adjoint matrices that almost commute with respect to the rank metric, then one can find commuting matrices C and D which are close in the rank metric to the matrices A and B respectively.
