Statement. Suppose A is an invertible square matrix and u, v are column vectors.Then the matrix determinant lemma states that (+) = (+) ().Here, uv T is the outer product of two vectors u and v. The theorem can also be stated in terms of the adjugate matrix of A: (+) = + (),in which case it applies whether or not the square matrix A is invertible.. Proof ...

The determinant of matrix is the sum of products of the elements of any row or column and their corresponding co-factors.The determinant of matrix is defined only for square matrices. For any square matrix A, the determinant of A is denoted by det A (or) |A|.It is sometimes denoted by the symbol Δ.The process of calculating the determinants of 1x1 matrices and 2x2 matrices is …

A formula for the determinant of a sum of matrices C. Reutenauer, M. Schützenberger Published 1 May 1987 Mathematics Letters in Mathematical Physics We give a formula, involving circular words and symmetric functions of the eigenvalues, for the determinant of a sum of matrices. Theorem of Hamilton-Cayley is deduced from this formula.

The determinant of a positive definite matrix G is proportional to ( 1 / Volume ( B ( G))) 2 where B ( G) denotes the unit ball with respect to the metric defined by G. If A and B are positive definite then the volume of B ( A + B) is smaller than the volume of B ( A) or B ( B). Show activity on this post. V k is any k-dimentional subspace of R ...

/ on matrices is also considered. 1. INTRODUCTION We are interested in estimating the determinant of the sum of two square matrices over F = R or C given some partial information about them. For two square matrices A and B, it is well-known that knowing det(A) and det(B) gives no knowledge of det(A + B).
