WebFor a proper BIB design, Fisher’s inequality b ≥ υ, or equivalently r ≥ k, holds. A BIB design is said to be symmetric if υ = b, and consequently r = k. Such a design is called a symmetric (υ, k, λ) design, and λ(υ − 1) = k(k − 1). A necessary condition for the existence of a symmetric (υ, k, λ) design is given by the ... WebJul 6, 2024 · Lastly, Fisher’s inequality itself is an important result which has several further extensions as well as applications to other interesting theorems yet to be formalised.

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.
