The inverse of a non-singular free matrix

The inverse matrix M−1 of a non-singular free matrix M need not be free. In this paper, we present several necessary and sufficient conditions for M−1 to be free. © 2001 Elsevier Science Inc. All rights reserved. AMS classification: 15A33; 15A09; 05C50

Singular matrix Darboux transformations in the inverse-scattering method

Singular Darboux transformations, in contrast to the conventional ones, have a singular matrix as a coefficient before the derivative. We incorporated such transformations into a chain of conventional transformations and presented determinant formulas for the resulting action of the chain. A determinant representation of the Kohlhoff–von Geramb solution to the Marchenko equation is given. PACS ...

Ela the Moore - Penrose Inverse of a Free Matrix

A matrix is free, or generic, if its nonzero entries are algebraically independent. Necessary and sufficient combinatorial conditions are presented for a complex free matrix to have a free Moore-Penrose inverse. These conditions extend previously known results for square, nonsingular free matrices. The result used to prove this characterization relates the combinatorial structure of a free matr...
