Log-concavity of some independence polynomials via a partial ordering
Log-concavity of some independence polynomials via a partial ordering is a scholarly work, published in 2019 in ''Discrete Mathematics''. The main subjects of the publication include multiple zeta function, graph, combinatorics, polynomial, spectral graph theory, node, discrete mathematics, independent events, mathematics, and unimodality. The authors apply some results on the log-concavity of combinations of log-concave sequences toward establishing the log-concavity (and, thus, the unimodality) of the independence numbers of some families of trees and related graphs.
