Expectational Equilibria and Drèze Equilibria in Many‐to‐One Matching Models

open access: yesJournal of Public Economic Theory, Volume 27, Issue 3, June 2025.
ABSTRACT We study coalition formation in many‐to‐one matching models from a competitive equilibrium perspective. We cover both models with and models without monetary transfers. A first notion to do so is the one of Drèze equilibrium, which we extend to the many‐to‐one setup. A second concept is expectational equilibrium.

Wall‐crossing for quasimaps to GIT stack bundles

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 6, June 2025.
Abstract We define the notion of ε$\epsilon$‐stable quasimaps to a GIT stack bundle, and study the wall‐crossing behavior of the resulting ε$\epsilon$‐quasimap theory as ε$\epsilon$ varies.

Limits of saturated ideals

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 6, June 2025.
Abstract We investigate the question of when a given homogeneous ideal is a limit of saturated ones. We provide cohomological necessary criteria for this to hold and apply them to a range of examples. In small cases, we characterise the limits. We also supply a number of auxiliary results on the classical and multigraded Hilbert schemes, for example ...

A Jordan–Chevalley decomposition beyond algebraic groups

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 6, June 2025.
Abstract We prove a decomposition of definable groups in o‐minimal structures generalizing the Jordan–Chevalley decomposition of linear algebraic groups. It follows that any definable linear group G$G$ is a semidirect product of its maximal normal definable torsion‐free subgroup N(G)$\mathcal {N}(G)$ and a definable subgroup P$P$, unique up to ...

Hausdorff dimensions of irreducible Markov hom tree‐shifts

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 6, June 2025.
Abstract This paper features a Cramér's theorem for finite‐state Markov chains indexed by rooted d$d$‐trees, obtained via the method of types in the classical analysis of large deviations. Along with the theorem comes two applications: an almost‐sure type convergence of sample means and a formula for the Hausdorff dimension of the symbolic space ...

The Picard group in equivariant homotopy theory via stable module categories

open access: yesJournal of Topology, Volume 18, Issue 2, June 2025.
Abstract We develop a mechanism of “isotropy separation for compact objects” that explicitly describes an invertible G$G$‐spectrum through its collection of geometric fixed points and gluing data located in certain variants of the stable module category.
