Trace formula for nuclear perturbations of discrete nonselfadjoint operatorsDarko Milinkovi{\cj}Matematicki fakultet, Beograd, YugoslaviaAbstract: It is shown that, if $T$ is a discrete nonselfadjoint operator, and $P$ is nuclear, than, under some condition, $T + P$ is discrete. A regularized trace formula is given. It is shown that this result is applicable to differential operators given by regular boundary conditions.
