Involutions and coninvolutions
Kh. D. Ikramov Lomonosov Moscow State University, Russia
Abstract:
A review of the relatively little-known matrix class, called coninvolutions, is given. The properties of these matrices are compared with those of the well studied involutory matrices or, briefly, involutions.
Key words:
similarities, congruences, involutions, coninvolutions, unitarily quasi-diagonalizable matrices, congruence-normal matrices.
