On a New Type of Unitoid Matrices

The cosquare of a nonsingular complex matrix is defined as in theory of -congruences and as in theory of Hermitian congruences. There is one more product of a similar kind, namely, . In this paper, we discuss the following question: Is it possible to interpret such a product as a cosquare within som...

Description
Summary:The cosquare of a nonsingular complex matrix is defined as in theory of -congruences and as in theory of Hermitian congruences. There is one more product of a similar kind, namely, . 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?
