Characterizing and generalizing cycle completable graphs

Combinatorics 2023-09-06 v2

Abstract

The family of cycle completable graphs has several cryptomorphic descriptions, the equivalence of which has heretofore been proven by a laborious implication-cycle that detours through a motivating matrix completion problem. We give a concise proof, partially by introducing a new characterization. Then we generalize this family to ``kk-quasichordal'' graphs, with three natural characterizations.
