Dimension reduction for optimal design problems with Kronecker product structure

open access: yesScandinavian Journal of Statistics, Volume 53, Issue 2, Page 763-797, June 2026.
Abstract This paper is motivated by the problem of optimal allocation of trials in multi‐environment crop variety testing with a large number of varieties. Optimizing the allocation of trials results in the minimization of a design criterion with a Kronecker product structure in the information matrix.

A characterization of metaplectic time–frequency representations

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We characterize all time–frequency representations that satisfy a general covariance property: any weak*‐continuous bilinear mapping that intertwines time–frequency shifts on the configuration space with time–frequency shifts on phase space is a multiple of a metaplectic time–frequency representation. This characterization offers an intrinsic,

Efficient Deconvolution in Populational Inverse Problems

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 9, 15 May 2026.
ABSTRACT This work is focused on the inversion task of inferring the distribution over parameters of interest, leading to multiple sets of observations. The potential to solve such distributional inversion problems is driven by the increasing availability of data, but a major roadblock is blind deconvolution, arising when the observational noise ...
