Title:Orthogonal Realizations of Random Sign Patterns
abstract:
A sign pattern S is a (+,-,0)-matrix whose entries represent positive, negative, and zero entries of a real matrix. We are interested in sign patterns that allow orthogonality, i.e., sign patterns S for which there exists a row orthogonal real matrix whose entries have the same sign as the corresponding entries in S. This talk investigates the probability that a random sign pattern allows orthogonality.
