On the unimodality of independence polynomials of some graphs
Wang, Yi · Zhu, Bao-Xuan
Original · EN
In this paper we study unimodality problems for the independence polynomial of a graph, including unimodality, log-concavity and reality of zeros. We establish recurrence relations and give factorizations of independence polynomials for certain classes of graphs. As applications we settle some unimodality conjectures and problems.
