dc.description.abstract | In this short note, we construct a nonsingular matrix A whose graph is a double star of order n >= 4 with n - 2 P-vertices. This example leads to a positive answer, for n >= 6, to a last open question proposed recently by Kim and Shader regarding the trees for which each nonsingular matrix has at most n 2 - P-vertices. | en |
