Bounded ratios for Lorentzian polynomials

Aayush Bathija, Prince Rohatgi, Daniel Soskin

We study multiplicative inequalities among the coefficients of Lorentzian polynomials through the notion of bounded ratios. Our main structural result completely characterizes the…

On the largest Littlewood--Richardson coefficient

Igor Pak, Daniel Soskin

We study partitions which attain the largest Littlewood-Richardson coefficient. More precisely, we prove that the largest is attained at partitions such that $μ\subseteq…

Correlation inequalities for Schur positivity

Swee Hong Chan, Hong Chen, Igor Pak +1

We generalize the Ahlswede--Daykin inequality (1978) to a Schur positive \emph{ADS inequality}, which also contains the Lam--Postnikov--Pylyavskyy inequality (2007) as a special ca…

Hadamard Products of dual Jacobi-Trudi matrices

Robert Angarone, Jang Soo Kim, Jaeseong Oh +1

We study positivity properties of Hadamard products of Jacobi-Trudi matrices. Maló proved that the Hadamard (entrywise) product of two totally positive upper-triangular Toeplitz ma…

Bounded ratios for Lorentzian matrices

Daoji Huang, June Huh, Daniel Soskin +1

We study multiplicative inequalities among entries of Lorentzian matrices, referred to as bounded ratios. These inequalities can be viewed as generalizations of the classical Alexa…

Generalized Diagonals in Positive Semi-Definite Matrices

Robert Angarone, Daniel Soskin

We describe all inequalities among generalized diagonals in positive semi-definite matrices. These turn out to be governed by a simple partial order on the symmetric group. This pr…

Multiplicative Inequalities In Cluster Algebras Of Finite Type

Michael Gekhtman, Zachary Greenberg, Daniel Soskin

Generalizing the notion of a multiplicative inequality among minors of a totally positive matrix, we describe, over full rank cluster algebras of finite type, the cone of Laurent m…

Permanental inequalities for totally positive matrices

Mark Skandera, Daniel Soskin

We characterize ratios of permanents of (generalized) submatrices which are bounded on the set of all totally positive matrices. This provides a permanental analog of results of Fa…

Plücker inequalities for weakly separated coordinates in totally nonnegative Grassmannian

Daniel Soskin, Prateek Kumar Vishwakarma

We show that the partial sums of the long Plücker relations for pairs of weakly separated Plücker coordinates oscillate around on the totally nonnegative part of the Grassmanni…

Barrett-Johnson inequalities for totally nonnegative matrices

Mark Skandera, Daniel Soskin

Given a matrix , let denote the submatrix of determined by rows and columns . Fischer's Inequalities state that for each Hermitian positive sem…

On bounded ratios of minors of totally positive matrices

Daniel Soskin, Michael Gekhtman

We provide several examples of bounded Laurent monomials of minors of a totally positive matrix, which can not be factored into a product of so called primitive ratios, thus showin…

Asymptotic Properties of the p-Adic Fractional Integration Operator

Anatoly N. Kochubei, Daniel S. Soskin

We study asymptotic properties of the p-adic version of a fractional integration operator introduced in the paper by A. N. Kochubei, Radial solutions of non-Archimedean pseudo-diff…
