Global dimension of dg algebras via compact silting objects
Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract We introduce a notion of global dimension for a triangulated category relative to a compact silting object. We prove that the finiteness of this dimension is an intrinsic property of the triangulated category itself and, therefore, independent of the choice of the silting object.

Spectral Characterization Of Sums Of Commutators II
, 1998 For countably generated ideals, J , of B(H), geometric stability is necessary for the canonical spectral characterization of sums of (J ; B(H))-commutators to hold. This answers a question raised by Dykema, Figiel, Weiss and Wodzicki.

A zero–one law for the spectral gap property of pairs in SU(2)$\mathrm{SU}(2)$
Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.Abstract For n⩾2$n \geqslant 2$, Gamburd, Jakobson, and Sarnak [J. Eur. Math. Soc. 1 (1999), 51–85] conjectured that almost every n$n$‐tuple in SU(2)$\mathrm{SU}(2)$ has a spectral gap. Toward this conjecture, Fisher [Int. Math. Res. Not. (2006), Art. ID 26028] established a zero–one law for n⩾3$n \geqslant 3$, but obtained only a partial result for n ...

Matchings: Source, goal, and faithful companion
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract Matchings were among the earliest motivations for graph theory. They subsequently remained a central goal, inspiring the development of new mathematical tools that went well beyond problems directly concerning matchings. These tools proved widely applicable, accompanying the growth of graph theory over the past century.

Mixed motives and linear forms in the Catalan constant
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract We first give a geometric construction of a two‐dimensional mixed motive over Q${\mathbb {Q}}$ with the Catalan constant G=1−1/32+1/52−1/72+⋯${\mathbf {G}}=1-1/3^2+1/5^2-1/7^2+\cdots$ as a period. We then use this motive to obtain a supply of linear forms in 1 and G${\mathbf {G}}$.

The Boolean spectrum of a Grothendieck category
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract A notion of support for objects in any Grothendieck category is introduced. This is based on the spectral category of a Grothendieck category and uses its Boolean lattice of localising subcategories. The support provides a classification of all subcategories that are closed under arbitrary coproducts, subobjects, and essential extensions ...

Bordered Floer homology, handlebody detection, and compressing diffeomorphisms
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract We show that, up to connected sums with integer homology L$L$‐spaces, bordered Floer homology detects handlebodies, as well as whether a mapping class extends over a given handlebody or compression body. Using this, we combine ideas of Casson–Long with the theory of train tracks to give an algorithm using bordered Floer homology to detect ...

bk$b^k$‐Algebroids and the variety of foliation jets
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract We introduce and classify singular foliations of bk+1$b^{k+1}$‐type, which formalize the properties of vector fields that are tangent to a submanifold W⊂M$W \subset M$ to order k$k$. When W$W$ is a hypersurface, these structures are Lie algebroids generalizing the bk+1$b^{k+1}$‐tangent bundles introduced by Scott.
