String topology via the coHochschild complex and local intersections
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract We construct an algebraic model for the Chas–Sullivan product and the Goresky–Hingston coproduct in string topology. The construction takes as its initial input a simplicial complex equipped with a local pairing on its simplicial chains, for instance, a homology manifold with its local intersection pairing.

Local Cohomology and ?ech Complexes [PDF]
, 2011 [[abstract]]讓 (R，m) 是一個 Noetherian local ring 以及讓C是關於這一個sequence x1，x2，…，xn 的?ech complex。如果這個ideal ( x1，x2，…，xn) 是m-primary，那麼我們知道 local cohomology 跟?ech complex 會有某種的同構關係。在本篇論文裡，我們會針對這個已知的事實給一個完整的證明。

Pairings, duality, amenability and bounded cohomology
, 2012 We give a new perspective on the homological characterisations of amenability given by Johnson and Ringrose in the context of bounded cohomology and by Block and Weinberger in the context of uniformly finite homology.

Integral cohomology and chern classes of the special linear group over the ring of integers [PDF]
, 2001 This paper is devoted to the complete calculation of the additive structure of the 2-torsion of the integral cohomology of the innite special linear group SL(Z) over the ring of integers Z.

Prismatic F‐crystals and Wach modules
Proceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.Abstract We show that the category of analytic/completed prismatic F-crystals$F\text{-crystals}$ on the absolute prismatic site of a small (unramified at p$p$) base ring is naturally equivalent to the category of relative Wach modules from the theory of (φ,Γ)-modules$(\varphi, \Gamma)\text{-modules}$.

Cominimaxness properties of formal local cohomology modules
, 2020 Let $\mathfrak{a}$ be an ideal of local ring $(R,\mathfrak{m})$ and $M$ a finitely generated $R$-module and $n\in\Bbb N$. It is shown that some results concerning cominimaxness of formal local cohomology modules.

The L-two cohomology of Artin groups
, 2003 For each Artin group we compute the reduced ℓ2-cohomology of its 'Salvetti complex'. This is a CW-complex which is conjectured to be a model for the classifying space of the Artin group. When this conjecture is known to hold our calculation describes the

Pitfalls and missing links in current understanding of 4D genomes
Quantitative Biology, Volume 14, Issue 2, June 2026.Abstract The spatial and temporal organization of the genome—collectively termed the 4D genome—is pivotal for regulating gene expression, maintaining genome stability, and guiding development. The convergence of chromosome conformation capture technologies, super‐resolution microscopy, and single‐cell epigenomics has transformed our understanding of ...

Twisted Poincare duality for some quadratic Poisson algebras [PDF]
, 2007 We exhibit a Poisson module restoring a twisted Poincaré duality between Poisson homology and cohomology for the polynomial algebra R=C[X1Xn] endowed with Poisson bracket arising from a uniparametrised quantum affine space.

On the $\partial\overline{\partial}$ -Lemma and Bott-Chern cohomology [PDF]
, 2013 On a compact complex manifold X, we prove a Frölicher-type inequality for Bott-Chern cohomology and we show that the equality holds if and only if X satisfies the ...
