In mathematics, Fischer's inequality gives an upper bound for the determinant of a positive-semidefinite matrix whose entries are complex numbers in terms of the determinants of its principal diagonal blocks. Suppose A, C are respectively p×p, q×q positive-semidefinite complex matrices and B is a p×q complex … See more Assume that A and C are positive-definite. We have $${\displaystyle A^{-1}}$$ and $${\displaystyle C^{-1}}$$ are positive-definite. Let We note that See more • Hadamard's inequality See more If M can be partitioned in square blocks Mij, then the following inequality by Thompson is valid: $${\displaystyle \det(M)\leq \det([\det(M_{ij})])}$$ where [det(Mij)] is the matrix whose (i,j) entry is det(Mij).
