Abstract
In this paper, we introduce a subclass of chordal graphs which contains d-trees and show that their complement are vertex
decomposable and so is shellable and sequentially Cohen-Macaulay. This result improves the main result of Ferrarello who used a theorem due to Fr¨oberg and extended a recent result of Dochtermann and Engstr¨om.
