Web1 Suppose you have a complex-valued rank-2 tensor of the form: A = [ a 11 a 12 a 21 a 22] where a i j ∈ C are complex numbers. If the phase ( ϕ i j) of a i j is bounded (for example, bounded on 0 < ϕ i j < π / 2 ), then will the phase of d e t ( A) also be bounded? I define the determinant as d e t ( A) = a 11 a 22 − a 21 a 12 WebA matrix A = aij is called a complex matrix if every entry aij is a complex number. The notion of conjugationfor complex numbers extends to matrices as follows: Deﬁne the conjugate of A= aij to be the matrix A= aij obtained from A by conjugating every entry. Then (using Appendix A) A+B=A+B and AB=AB holds for all (complex) matrices of ...
