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 matrix. Let so that M is a (p+q)×(p+q) matrix. solcer house walesWebFisher’s Inequality If a balanced incomplete block design is speciﬁed with param eters (v,b,r,k,λ) then v ≤ b.
