On isometry groups of self-adjoint traceless and skew-symmetric matrices
M Gaál, RM Guralnick - Linear Algebra and its Applications, 2018 - Elsevier
This note is concerned with isometries on the spaces of self-adjoint traceless matrices. We
compute the group of isometries with respect to any unitary similarity invariant norm. This …
