Centralizers of elements in the orthogonal, symplectic and unitary groups

Tadej Starčič

We explicitly compute and parametrize the centralizers of elements, encompassing dege\-ne\-rate and unipotent ones, in the orthogonal, symplectic, and unitary gro\-ups over the rea…

Stein neighborhood bases of embedded strongly pseudoconvex domains and approximation of mappings

Tadej Starčič

In this paper we construct a Stein neighborhood basis for any compact subvariety $A$ with strongly pseudoconvex boundary $b A$ and Stein interior $A \ b A$ in a complex space…

Isotropy groups of the action of orthogonal *congruence on Hermitian matrices

Tadej Starčič

We present a procedure which enables the computation and the description of structures of isotropy subgroups of the group of complex orthogonal matrices with respect to the action…

Isotropy groups of the action of orthogonal similarity on symmetric matrices

Tadej Starčič

We find an algorithmic procedure that enables to compute and to describe the structure of the isotropy subgroups of the group of complex orthogonal matrices with respect to the act…

On structures of normal forms of complex points of small $C^{2}$ -perturbations of real $4$ -manifolds embedded in a complex $3$ -manifold

Tadej Starčič

We extend our previous result on the behavior of the quadratic part of a complex points of a small $C^{2}$ -perturbation of a real $4$ -manifold embedded in a complex $3$ -m…

On regular Stein neighborhoods of a union of two maximal totally real subspaces in $C^{n}$

Tadej Starčič

We present a construction of regular Stein neighborhoods of a union of maximally totally real subspaces $M = (A + i I) R^{n}$ and $N = R^{n}$ in $C^{n}$ , provided that…
