Abstract

The matrix equations KK  I and KK  I are important in the theory of
con-s-similarity. For the first equation, a characterization of solutions was
given in Section 4.6 of Matrix Analysis by Horn and Johnson. Since this
characterization is not constructive, a complete and constructive description
of solutions to these equations is derived under one of the following
assumptions: (a) K is a s-normal matrix, or (b) K is a con-s-normal matrix.
