Determinant of a Complex Matrix

  1. Aug 26, 2011 #1

    Is det(A*)=(det(A))*, and why? Here ()* means complex conjugate only, and A is a complex matrix.

    Thanks in advance

    Yes. The determinant is a polynomial with real coefficients of the entries in A, and for any polynomial p in n variables with real coefficients, p(x_1*, x_2*, ... , x_n*) = p(x_1, x_2, ... , x_n)*.
