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.

On profinite rigidity amongst free‐by‐cyclic groups I: The generic case

open access: yesProceedings of the London Mathematical Society, Volume 130, Issue 6, June 2025.
Abstract We prove that amongst the class of free‐by‐cyclic groups, Gromov hyperbolicity is an invariant of the profinite completion. We show that whenever G$G$ is a free‐by‐cyclic group with first Betti number equal to one, and H$H$ is a free‐by‐cyclic group which is profinitely isomorphic to G$G$, the ranks of the fibres and the characteristic ...

On Rainbow Turán Densities of Trees

open access: yesRandom Structures &Algorithms, Volume 66, Issue 3, May 2025.
ABSTRACT For a given collection 𝒢=(G1,…,Gk) of graphs on a common vertex set V$$ V $$, which we call a graph system, a graph H$$ H $$ on a vertex set V(H)⊆V$$ V(H)\subseteq V $$ is called a rainbow subgraph of 𝒢 if there exists an injective function ψ:E(H)→[k]$$ \psi :E(H)\to \left[k\right] $$ such that e∈Gψ(e)$$ e\in {G}_{\psi (e)} $$ for each e∈E(H)$$

Hodge loci associated with linear subspaces intersecting in codimension one

open access: yesMathematische Nachrichten, Volume 298, Issue 4, Page 1220-1229, April 2025.
Abstract Let X⊂P2k+1$X\subset \mathbf {P}^{2k+1}$ be a smooth hypersurface containing two k$k$‐dimensional linear spaces Π1,Π2$\Pi _1,\Pi _2$, such that dimΠ1∩Π2=k−1$\dim \Pi _1\cap \Pi _2=k-1$. In this paper, we study the question whether the Hodge loci NL([Π1]+λ[Π2])$\operatorname{NL}([\Pi _1]+\lambda [\Pi _2])$ and NL([Π1],[Π2])$\operatorname{NL ...
