Title: Decomposition and scaling-inequality for line-sum-symmetric nonnegative matrices

Technical Report ·
OSTI ID:5436047

A matrix B is called line-sum-symmetric if it is square and the sum of elements in each row of B equals the sum of elements in the corresponding column. Results from the theory of network flows are used to obtain a decomposition of nonnegative line-sum-symmetric matrices. The decomposition is employed to prove the following inequality: Assume D(x)AD(y) is line-sum-symmetric where A is a square, nonnegative matrix and D(x) and D(y) are diagonal matrices whose diagonal elements are the coordinates of the nonnegative vectors x and y, respectively. Then y/sup T/Ax greater than or equal to x/sup T/Ay.
