**Title: Almost commuting matrices with respect to the rank metric **

**Abstract: I will present my recent result with Gabor Elek, which 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. **
