Existence and orthogonality of stable envelopes for bow varieties

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract Stable envelopes, introduced by Maulik and Okounkov, provide a family of bases for the equivariant cohomology of symplectic resolutions. They are part of a fascinating interplay between geometry, combinatorics and integrable systems. In this expository article, we give a self‐contained introduction to cohomological stable envelopes of type A$A$

Compactifications of strata of differentials

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract In this informal expository note, we quickly introduce and survey compactifications of strata of holomorphic 1‐forms on Riemann surfaces, that is, spaces of translation surfaces. In the last decade, several of these have been constructed, studied, and successfully applied to problems.

Bounded cohomology of groups acting on trees with almost prescribed local actions

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract We prove the vanishing of bounded cohomology of the groups acting on trees with almost prescribed local actions G(F,F′)$G(F, F^{\prime })$, where F

Arithmetic sparsity in mixed Hodge settings

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract Let X$X$ be a smooth irreducible quasi‐projective algebraic variety over a number field K$K$. Suppose X$X$ is equipped with a p$p$‐adic étale local system compatible with an admissible graded‐polarized variation of mixed Hodge structures on the complex analytification of XC$X_{\operatorname{\mathbb {C}}}$.
