Abstract
Over the last decades checking copositivity of matrices by simplicial subdivision of the unit simplex has made a big progress. Recently it has been showing that surprisingly the use of regular sim-plicial subdivisions may have some advantage over traditional iterative bisection of simplices. In this contribution we pose the question whether regular subdivisions may provide opportunities in copositivity testing.
