Biharmonic hypersurfaces in the standard Lorentz 5-pseudosphere [PDF]
Journal of Mahani Mathematical ResearchIn this manuscript, we study the Lorentz hypersurfaces of the Lorentz 5-pseudosphere (i.e. the pseudo-Euclidean 5-sphere) $S^5_1$ having three distinct principal curvatures.

Background Instability of Quintessence Model in Light of Entropy and Distance Conjecture
Fortschritte der Physik, Volume 74, Issue 6, June 2026.ABSTRACT We apply the covariant entropy bound argument supporting the de Sitter swampland conjecture to the quintessence model, to find out the condition for the background to be unstable. More concretely, the background is unstable when the matter entropy given by the species number of the effective field theory increases more rapidly than the ...

Some structure theorems for Weingarten surfaces
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract Let M⊂R3$M\subset \mathbb {R}^3$ be a properly embedded, connected, complete surface with boundary a convex planar curve C$C$, satisfying an elliptic equation H=f(H2−K)$H=f(H^2-K)$, where H$H$ and K$K$ are the mean and the Gauss curvature, respectively—which we will refer to as Weingarten equation.

Singularities of null mean curvature flow of null hypersurfaces in Lorentzian manifolds
, 2019 We classify two main singularities, as type I and type II, associated with null mean curvature flow of screen conformal null hypersurfaces in Lorentzian manifolds.

Integral formulas for closed spacelike hypersurfaces in anti-de Sitter space $H_1^{n+1}(-1)$ [PDF]
, 2007 summary:In this paper, we study closed $k$-maximal spacelike hypersurfaces $M^n$ in anti-de Sitter space $H_1^{n+1}(-1)$ with two distinct principal curvatures and give some integral formulas about these ...

The singularity category and duality for complete intersection groups
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract If G$G$ is a finite group, the structure of the modular representation theory depends on the cochains C∗(BG;k)$C^*(BG; k)$, viewed as a commutative ring spectrum. We consider here its singularity category (in the sense of the author and Stevenson [Adv. Math.

On the Milnor fibres of initial forms of topologically equivalent holomorphic functions
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract Budur, Fernández de Bobadilla, Le, and Nguyen in 2022 conjectured that if two germs of holomorphic functions are topologically equivalent, then the Milnor fibres of their initial forms are homotopy equivalent. In this paper, we give an affirmative answer to this conjecture in the case of plane curves.

The length of the second fundamental form, a tangency principle and applications
Anais da Academia Brasileira de Ciências, 2004 In this paper we prove a tangency principle (see Fontenele and Silva 2001) related with the length of the second fundamental form, for hypersurfaces of an arbitrary ambient space.

Maximum number of zeroes of polynomials on weighted projective spaces over a finite field
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract We compute the maximum number of rational points at which a homogeneous polynomial can vanish on a weighted projective space over a finite field, provided that the first weight is equal to 1. This solves a conjecture by Aubry, Castryck, Ghorpade, Lachaud, O'Sullivan and Ram, which stated that a Serre‐like bound holds with equality for weighted
