Centralizers of the complex orthogonal and symplectic group
Tadej Starčič
We find a recursive algorithm for computing the precise centralizers of the complex orthogonal and symplectic groups, and hence the isotropy groups, with respect to the similarity…

Isotropy groups of the action of orthogonal similarity on skew-symmetric and on complex orthogonal matrices
Tadej Starčič
We compute and analyze isotropy subgroups of the complex orthogonal group with respect to the similarity transformation on itself and on skew-symmetric matrices. Their group struct…

The stabilizers for the action of orthogonal similarity on symmetric matrices and orthogonal -conjugacy on Hermitian matrices
Tadej Starčič
We describe the recursive algorithmic procedure to compute the stabilizers of the group of complex orthogonal matrices with respect to the action of similarity on the set of all sy…
