Compact and finite‐type support in the homology of big mapping class groups
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract For any infinite‐type surface S$S$, a natural question is whether the homology of its mapping class group contains any non‐trivial classes that are supported on (i) a compact subsurface; or (ii) a finite‐type subsurface. Our purpose here is to study this question, in particular giving an almost‐complete answer when the genus of S$S$ is ...

Interactions between universal composition operators and complex dynamics
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract This paper is concerned with universality properties of composition operators Cf$C_f$, where the symbol f$f$ is given by a transcendental entire function restricted to parts of its Fatou set. We determine universality of Cf$C_f$ when f$f$ is restricted to (subsets of) Baker and wandering domains.

Deformations of Anosov subgroups: Limit cones and growth indicators
Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.Abstract Let G$G$ be a connected semisimple real algebraic group. We prove that limit cones vary continuously under deformations of Anosov subgroups of G$G$ under a certain convexity assumption, which turns out to be necessary. We apply this result to the notion of sharpness for the action of a discrete subgroup on a non‐Riemannian homogeneous space ...

Random walk on sphere packings and Delaunay triangulations in arbitrary dimension
Proceedings of the London Mathematical Society, Volume 131, Issue 3, September 2025.Abstract We prove that random walks on a family of tilings of d$d$‐dimensional Euclidean space, with a canonical choice of conductances, converge to Brownian motion modulo time parameterization. This class of tilings includes Delaunay triangulations (the dual of Voronoi tessellations) and sphere packings.

A lower bound on volumes of end‐periodic mapping tori
Journal of Topology, Volume 18, Issue 3, September 2025.Abstract We provide a lower bound on the volume of the compactified mapping torus of a strongly irreducible end‐periodic homeomorphism f:S→S$f: S \rightarrow S$. This result, together with work of Field, Kim, Leininger, and Loving [J. Topol. 16 (2023), no.

ChemBioChem, Volume 26, Issue 15, August 22, 2025.A unique chemoenzymatic synthesis route toward (S)‐baclofen is presented, which highlights a hydroformylation and biocatalysis step toward the synthesis of such a challenging β‐chiral amino acid. The shown methodology exhibits high conversions and enantiomeric excess and is transferable to other β‐chiral amines and amino acids.

A Hausdorff HS-space which is not regular [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 1998 In this paper I disprove, with a counterexample, a theorem of H.J. Schmidt [6], which states that each Hausdorff HS-space is regular. M. Paoli and E. Ripoli [4] noted that the proof of this theorem is incorrect, but they left the statement open.
