    On the betti numbers of some classes of binomial edge ideals
    (the electronic journal of combinatorics, 2013) Sohail Zafar; Zohaib Zahid
    We study the Betti numbers of binomial edge ideal associated to some classes of graphs with large Castelnuovo-Mumford regularity. As an application we give several lower bounds of the Castelnuovo-Mumford regularity of arbitrary graphs depending on induced subgraphs.
