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.

Polar Varieties and Efficient Real Equation Solving: The Hypersurface Case
, 1996 The objective of this paper is to show how the recently proposed method by Giusti, Heintz, Morais, Morgenstern, Pardo [10] can be applied to a case of real polynomial equation solving.

3×4: a telematic/architectural hypersurface [PDF]
, 2017 In her 2004 publication ‘Virtual Theatres’ Gabriella Giannachi wrote on the processes of doubling presence in interactive artworks, from liquid architecture to telematic performance, where the physical and virtual realms meet and intersect at a place she

Sharp restriction estimates for some degenerate higher codimensional quadratic surfaces
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract The Fourier restriction conjecture is a fundamental problem in harmonic analysis. In this paper, we investigate restriction estimates for degenerate higher codimensional quadratic surfaces and obtain sharp results for some types of degenerate cases.

Two theorems on (ϵ)-Sasakian manifolds
International Journal of Mathematics and Mathematical Sciences, 1998 In this paper, We prove that every (ϵ)-sasakian manifold is a hypersurface of an indefinite kaehlerian manifold, and give a necessary and sufficient condition for a Riemannian manifold to be an (ϵ)-sasakian manifold.

Optimal bounds for local volumes of threefold singularities
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract We establish an optimal upper bound for local volumes of Gorenstein canonical non‐hypersurface threefold singularities. Specifically, we show that a klt threefold singularity with local volume at least 9 is either a hypersurface singularity or a quotient singularity.

On the CR automorphism group of a certain hypersurface of infinite type in ℂ2
, 2015 We consider (Formula presented.) -smooth real hypersurfaces of infinite type in (Formula presented.). The purpose of this paper is to give explicit descriptions for stability groups of the hypersurface (Formula presented.) and a radially symmetric ...

Wasserstein rigidity over Rn$\mathbb {R}^n$ with smooth norms
Mathematika, Volume 72, Issue 4, October 2026.Abstract We study p−Wasserstein$p-{\rm Wasserstein}$ spaces Wp(Rn,dN)$ \mathcal {W}_p(\mathbb {R}^n, d_N)$ over Rn$\mathbb {R}^n$ equipped with a norm metric dN$d_N$. We show that, if the norm is smooth enough, then the Wasserstein space is isometrically rigid whenever p≠2$p \ne 2$.

Machine Learning for Synthetic Organic Chemistry: Methods, Applications, and Best Practices
Angewandte Chemie Novit, Volume 2, Issue 3, September 2026.Artificial intelligence (AI) and machine learning (ML) are increasingly reshaping experimental chemistry. This review maps the challenges of synthetic organic chemistry to modern digital tools that can help address them. While focusing on the practical application of ML tools in real‐world laboratory settings, we outline prerequisites, emerging ...
