Combinatorial aspects of generalized complementary basic matrices
Miroslav Fiedler, Frank Hall (2013)
Open Mathematics
Similarity:
This paper extends some properties of the generalized complementary basic matrices, in particular, in a combinatorial direction. These include inheritance (such as for Alternating Sign Matrices), spectral, and sign pattern matrix (including sign nonsingularity) properties.
