WebThe determinant of a matrix polynomial with Hermitian positive-definite (semidefinite) coefficients is a polynomial with positive (nonnegative) coefficients. [1] Note that polynomial matrices are not to be confused with monomial matrices , which are simply matrices with exactly one non-zero entry in each row and column. Web1 day ago · Abstract. We consider families of skew-symmetric matrices depending analytically on parameters. We obtain necessary existence conditions and find normal forms for such families. The results ...
