Strict unimodality of plucking polynomials of rooted trees
Zhiyun Cheng , Sujoy Mukherjee , Józef H. Przytycki , Xiao Wang , Seung Yeop Yang
AbstractWe classify rooted trees which have strictly unimodal plucking polynomials (q-polynomials). We also give criteria for a trapezoidal shape of a plucking polynomial. We generalize results of Pak and Panova on strict unimodality of q-binomial coefficients.
