Resumo
The cosquare of a nonsingular complex matrix A is defined as A in theory of A-congruences and as A in theory of Hermitian congruences. There is one more product of a similar kind, namely, A. In this paper, we discuss the following question: Is it possible to interpret such a product as a cosquare within some theory of congruences? What is this theory and how does look its canonical form?
