Lower bounds for contingency tables via Lorentzian polynomials
Petter Brändén, Jonathan Leake, Igor Pak
We present a new lower bound on the number of contingency tables, improving upon and extending previous lower bounds by Barvinok and Gurvits. As an application, we obtain new lower…
A characterization of multiplier sequences for generalized Laguerre bases
Petter Brändén, Elin Ottergren
We give a complete characterization of multiplier sequences for generalized Laguerre bases. We also apply our methods to give a short proof of the characterization of Hermite multi…
Mesh patterns and the expansion of permutation statistics as sums of permutation patterns
Petter Brändén, Anders Claesson
Any permutation statistic $f:\sym\to\CC$ may be represented uniquely as a, possibly infinite, linear combination of (classical) permutation patterns: . To provide ex…
Lee-Yang Problems and The Geometry of Multivariate Polynomials
Julius Borcea, Petter Brändén
We describe all linear operators on spaces of multivariate polynomials preserving the property of being non-vanishing in open circular domains. This completes the multivariate gene…
Finite automata and pattern avoidance in words
Petter Brändén, Toufik Mansour
We say that a word on a totally ordered alphabet avoids the word if there are no subsequences in order-equivalent to . In this paper we suggest a new approach to the…
