Weighted veronese rings via convex semigroups

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.
Abstract We determine several properties of two‐dimensional normal affine semigroup rings, and in particular of weighted Veronese rings, including determinantal presentations, Gröbner bases, graded Hilbert series and graded Betti numbers, the structure of their associated graded rings, and their Koszul property.

Hyperbolicity and fundamental groups of complex quasi‐projective varieties (III): Applications

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.
Abstract This paper is Part III of a series of three. We begin by introducing the notion of h$h$‐special varieties, which can be seen as varieties “chain‐connected by the Zariski closures of entire curves.” We prove that if X$X$ is either a special smooth complex quasi‐projective variety in the sense of Campana or an h$h$‐special variety, then for any ...

Discrete homotopy hypothesis for n$n$‐types

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.
Abstract We show that discrete and classical homotopy theories are equivalent after localizing at n$n$‐equivalences for any non‐negative integer n$n$. By constructing an explicit homotopy inverse to the graph nerve functor associating an n$n$‐fibrant cubical set to a graph, we are also able to give explicit computations of several previously unknown ...
