Combinatorics 2024-05-30 v1

Abstract

We study sign symmetric P0,1+P_{0,1}^+-matrix completion problem. It is shown that any non-asymmetric incomplete digraph lacks sign symmetric P0,1+P_{0,1}^+-completion, digraphs of order at most four are completely classified and finally comparisons between sign symmetric P0,1+P_{0,1}^+-completion and other matrix completions was given.
