In 1985, Elsner provided an upper bound for the Hausdorff distance of the spectra of two matrices. In this talk I will extend his result to the infinite-dimensional setting proving an upper bound for the Hausdorff distance of the spectra of two trace class operators in terms of computationally accessible expressions.
