A New Class of Non-Linear Stability Preserving Operators

open access: yes, 2011
We extend Br\"and\'en's recent proof of a conjecture of Stanley and describe a new class of non-linear operators that preserve weak Hurwitz stability and the Laguerre-P\'olya class.Comment: Fixed typos, spelling, and updated links in ...

Interlacing Log-concavity of the Boros-Moll Polynomials [PDF]

open access: yes, 2010
We introduce the notion of interlacing log-concavity of a polynomial sequence $\{P_m(x)\}_{m\geq 0}$, where $P_m(x)$ is a polynomial of degree m with positive coefficients $a_{i}(m)$.

A Discontinuity in the Distribution of Fixed Point Sums

open access: yes, 2003
The quantity $f(n,r)$, defined as the number of permutations of the set $[n]=\{1,2,... n\}$ whose fixed points sum to $r$, shows a sharp discontinuity in the neighborhood of $r=n$.
