Wasserstein rigidity over Rn$\mathbb {R}^n$ with smooth norms

open access: yesMathematika, Volume 72, Issue 4, October 2026.
Abstract We study p−Wasserstein$p-{\rm Wasserstein}$ spaces Wp(Rn,dN)$ \mathcal {W}_p(\mathbb {R}^n, d_N)$ over Rn$\mathbb {R}^n$ equipped with a norm metric dN$d_N$. We show that, if the norm is smooth enough, then the Wasserstein space is isometrically rigid whenever p≠2$p \ne 2$.

Well‐posedness of heat equations with nonlinearities of arbitrarily rapid growth

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 3, September 2026.
Abstract We address local‐ and global‐in‐time well‐posedness of the Cauchy problem for nonlinear heat equations without imposing growth rate restrictions on the nonlinearity a priori. Our results constitute a nontrivial expansion of the classical Lq$L^q$‐theory for nonlinearities dominated by polynomial growth and the exponential‐Orlicz space theory ...

The Exact Inequalities of Jackson–Stechkin Type and the Width Values for Some Classes of Functions in L₂ Space

open access: yesМоделирование и анализ информационных систем, 2013
In this paper, some exact inequalities between the best approximations of periodic differentiable functions with trigonometric polynomials and generalized moduli of the continuity Ωm of m-th order in L₂[0, 2π] space are found.

Robust Bernoulli Mixture Models for Credit Portfolio Risk

open access: yesMathematical Finance, Volume 36, Issue 3, Page 528-543, July 2026.
ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...

The limit process of the difference between the empirical distribution function and its concave majorant

open access: yes, 2006
We consider the process –Fn, being the difference between the empirical distribution function Fn and its least concave majorant , corresponding to a sample from a decreasing density.

Influence of Coefficient Arguments on the Maximum Modulus of Entire Functions of Several Variables

open access: yesMathematics
This paper investigates how the phases, or arguments, of coefficients in multiple power series influence the maximum modulus of entire functions of several complex variables.

Engagement maximization

open access: yesTheoretical Economics, Volume 21, Issue 3, Page 849-887, July 2026.
We investigate the management of information provision to maximize user engagement. A principal sequentially reveals signals to an agent who has a limited amount of information processing capacity and can choose to exit at any time. We identify a “dilution” strategy—sending rare but highly informative signals—that maximizes user engagement.

Disrupted habenula function in major depression [PDF]

open access: yesMolecular Psychiatry, 2016
The habenula is a small, evolutionarily conserved brain structure that plays a central role in aversive processing and is hypothesised to be hyperactive in depression, contributing to the generation of symptoms such as anhedonia. However, habenula responses during aversive processing have yet to be reported in individuals with major depressive disorder

Tame majorant analyticity for the Birkhoff map of the defocusing nonlinear Schrödinger equation on the circle [PDF]

open access: yes, 2018
For the defocusing nonlinear Schrö dinger equation on the circle, we construct a Birkhoff map Φ which is tame majorant analytic in a neighborhood of the origin.
