Antilinear operators and special matrices
Kh. D. Ikramov M. V. Lomonosov Moscow State University, Moscow, Russia
Abstract:
The following facts are proved: (a) Concommutation of complex matrices means the conventional commutation of the antilinear operators defined by these matrices. (b) Symmetric, skew-symmetric, unitary, and conjugate-normal matrices interpreted as antilinear operators acting in the unitary space $\mathbb C^n$ are Hermitian, skew-Hermitian, unitary, and normal operators, respectively.
Key words and phrases:
unitary similarity, unitary congruence, antilinear operator, conjugate-normal matrix.
