Abstract: By gaving mutual determination relationship between quadratic matrix and quadratic polynomial, we obtained invariance of rank for generalized Jordan products of quadratic matrix and a new rank equations associated with quadratic matrix by means of matrix transformation. The results summarized and generalized the relevant results of the rank equations such as the (scalar) idempotent matrix, (scalar) involutory matrix, etc.

Key words: rank, quadratic matrix, invariance, Jordan product of matrix
