WebThis is known as Fisher's Inequality, since it was proven by Sir Ronald Aylmer Fisher (1890—1962). The proof we will give is somewhat longer than the standard proof. This is because the standard proof uses linear algebra, which we do not expect to be required background for this course. 🔗 Theorem 17.3.1 ( Fisher's Inequality).

"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).

Fisher's inequality is a necessary condition for the existence of a balanced incomplete block design, that is, a system of subsets that satisfy certain prescribed conditions in combinatorial mathematics. Outlined by Ronald Fisher, a population geneticist and statistician, who was concerned with the design of experiments such as studying the differences among several different varieties of plants, under each of a number of different growing conditions, called blocks.
