YANG–BAXTER FIELD FOR SPIN HALL–LITTLEWOOD SYMMETRIC FUNCTIONS

open access: yesForum of Mathematics, Sigma, 2019
Employing bijectivization of summation identities, we introduce local stochastic moves based on the Yang–Baxter equation for $U_{q}(\widehat{\mathfrak{sl}_{2}})$.

Plugin procedure in segmentation and application to hyperspectral image segmentation

open access: yes, 2010
In this article we give our contribution to the problem of segmentation with plug-in procedures. We give general sufficient conditions under which plug in procedure are efficient. We also give an algorithm that satisfy these conditions.

A representative sampling plan for auditing health insurance claims

open access: yes, 2007
A stratified sampling plan to audit health insurance claims is offered. The stratification is by dollar amount of the claim. The plan is representative in the sense that with high probability for each stratum, the difference in the average dollar amount ...

Self-avoiding walk is ballistic on graphs with more than one end

open access: yesForum of Mathematics, Sigma
We prove that on any transitive graph G with infinitely many ends, a self-avoiding walk of length n is ballistic with extremely high probability, in the sense that there exist constants $c,t>0$ such that $\mathbb {P}_n(d_G(w_0,w_n)\geq cn)\geq

Counting minimal cutsets and $p_c<1$

open access: yesForum of Mathematics, Pi
We prove two results concerning percolation on general graphs. • We establish the converse of the classical Peierls argument: if the critical parameter for (uniform) percolation satisfies ...

Degree-penalized contact processes

open access: yesForum of Mathematics, Sigma
In this paper we study degree-penalized contact processes on Galton-Watson (GW) trees and the configuration model. The model we consider is a modification of the usual contact process on a graph.

Scaling limit of soliton lengths in a multicolor box-ball system

open access: yesForum of Mathematics, Sigma
The box-ball systems are integrable cellular automata whose long-time behavior is characterized by soliton solutions, with rich connections to other integrable systems such as the Korteweg-de Vries equation.

Comment on the paper by Y.Komura and Y.Okabe [arXiv:1011.3321] [PDF]

open access: yes, 2011
We point out that the claim of strong universality in the paper J.Phys. A 44, 015002, arXiv:1011.3321 is incorrect, as it contradicts known rigorous results.Comment: submitted to J.Phys.
