Local Wintgen ideal submanifolds

This paper is dedicated to the local parametric classification of Wintgen ideal submanifolds in space forms. These submanifolds are characterized by the pointwise attainment of equality in the DDVV inequality, which relates the scalar curvature, the length of the mean curvature vector field and the normal curvature tensor.

The local hull of holomorphy of semirigid submanifolds of codimension two.

Michigan Mathematical Journal, 1987
Let \(M\subset {\mathbb{C}}^ n\) be a smooth generic, CR submanifold of codimension d, and let \(T^ C(M)\) and \(H^ C(M)\) be the complexified tangent bundle and the complexified holomorphic tangent bundles. For \(p\in M\), let \(L^ 0_ p(M)=H^ C_ p(M)\), and let \(L^ m_ p(M)\) be the subbundle generated by brackets of length j, i.e., \([L_ 1,[L_ 2,...,[

Visibility and Intersection Density for Boolean Models in Hyperbolic Space

Mathematische Nachrichten, Volume 299, Issue 9, Page 2542-2565, September 2026.
ABSTRACT For Poisson particle processes in hyperbolic space we introduce and study concepts analogous to the intersection density and the mean visible volume, which were originally considered in the analysis of Boolean models in Euclidean space. In particular, we determine a necessary and sufficient condition for the finiteness of the mean visible ...

Crystal Anisotropy Implications on the Magneto‐Optical Properties of van der Waals FePS3

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Crystal anisotropy in FePS3 due to a distorted FeS6 octahedron results in significant changes in its electronic and optical transitions. For the first time, four emission transitions are revealed with both linear and circular polarization responses down to the monolayer.

Singularity of non‐pluripolar cohomology classes

Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract We establish a relation between Lelong numbers and the full mass property of relative non‐pluripolar products. We use this relation to prove that if the restricted volume of a big class α$\alpha$ along an effective divisor D$D$ has full mass, then the Lelong numbers of the non‐pluripolar class ⟨αn−1⟩$\langle \alpha ^{n-1}\rangle$ at every ...

Eigenvalue Estimates for Submanifolds with Locally Bounded Mean Curvature

Annals of Global Analysis and Geometry, 2003
We give lower bounds for the first Dirichilet eigenvalues for domains in submanifolds with locally bounded mean curvatures. These bounds depend on the injectivity radius, sectional curvature (upperbound) of the ambient space and on the mean curvature of the submanifold.

Isometric immersions into three‐dimensional unimodular metric Lie groups

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.
