Skew shapes, Ehrhart positivity, and beyond

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract A classical result by Kreweras (1965) allows one to compute the number of plane partitions of a given skew shape and bounded parts as certain determinants. We prove that these determinants expand as polynomials with nonnegative coefficients.

On T -Schur Convex Maps [PDF]

open access: yes, 2020
We introduce and examine the notion of T-Schur convexity which is naturally connected with Schur convexity. As a particular case, we consider T-Wright convex maps which generalize a well-known and intensively investigated class of t-Wright convex ...

Measured‐State Conditioned Recursive Feasibility for Stochastic Model Predictive Control

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 11, Page 5964-5981, 25 July 2026.
ABSTRACT In this paper, we address the problem of designing stochastic model predictive control (SMPC) schemes for linear systems affected by unbounded disturbances. The contribution of the paper is rooted in a measured‐state initialization strategy. First, due to the nonzero probability of violating chance‐constraints in the case of unbounded noise ...

Computation of transfer function matrices of periodic systems [PDF]

open access: yes, 2002
We present a numerical approach to evaluate the transfer function matrices of a periodic system corresponding to lifted state-space representations as constant systems.

Convexity, Schur-Convexity and Bounds for the Gamma Function Involving the Digamma Function

open access: yesRocky Mountain Journal of Mathematics, 1998
With aid of, among others, Jensen-convex and Schur-convex functions the author offers considerable improvements on estimations of a shifted gamma function divided by the gamma function at the original place. In particular, considerable improvements on chains of inequalities in the paper of \textit{H. Alzer} [Math. Comput. 60, No.

Estimating a convex function in nonparametric regression [PDF]

open access: yes
A new nonparametric estimate of a convex regression function is proposed and its stochastic properties are studied. The method starts with an unconstrained estimate of the derivative of the regression function, which is firstly isotonized and then ...
