Abstract
- There are two motivation questions in \cite{MTS, MTS1} about Castelnuovo-Mumford regularity and vertex decomposable of simple graph $G$. In this paper, we disprove the questions by providing of two counterexamples.<br />Comment: 6 pages. to appear in International Electronic Journal of Algebra
