Abstract
A very well-covered graph is a well-covered graph without isolated vertices such that the size of its minimal vertex covers is half of the number of vertices. If is a Cohen-Macaulay very well-covered graph, we deeply investigate some algebraic properties of the cover ideal of via the Rees algebra associated to the ideal.
