Construction of the field of Norden — Timofeev planes of hypersurfacese quipped with distributions
Дифференциальная геометрия многообразий фигур, 2018 In the projective space the research of a hypersurface with three strongest mutual subbundles continues. The field of the invariant Norden — Timofeev planes is constructed that is internally attached to the hypersurface.

Lietuvos Matematikos Rinkinys, 2010 In this article we generalize some classical formulas for curvatures of hypersurfaces in the n-dimensional Euclidean space using the homogeneous formulas.

An Index Theorem for Modules on a Hypersurface Singularity [PDF]
, 2011 A topological interpretation of Hochster's Theta pairing of two modules on a hypersurface ring is given in terms of linking numbers. This generalizes results of M. Hochster and proves a conjecture of J. Steenbrink.

The three‐step test in international copyright—a global framework for generative AI training
American Business Law Journal, Volume 63, Issue 3, Page 265-298, Fall 2026.Abstract The training of generative artificial intelligence (genAI) models involves the processing of large datasets, which often include copyrighted materials, thereby raising questions of copyright infringement. These questions tend to center on whether such use constitutes fair use or falls under text and data mining (TDM) exceptions.

Some submersions of CR-hypersurfaces of Kaehler-Einstein manifold
International Journal of Mathematics and Mathematical Sciences, 2003 The Riemannian submersions of a CR-hypersurface M of a Kaehler-Einstein manifold M˜ are studied. If M is an extrinsic CR-hypersurface of M˜, then it is shown that the base space of the submersion is also a Kaehler-Einstein manifold.

Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.ABSTRACT High‐frequency seismic wave descriptions are essential for fundamental geophysical applications, including earthquake hypocenter location, magnitude estimation, and traveltime–amplitude tomography. These descriptions rely on two coupled PDEs: the eikonal equation (governing traveltimes) and the transport equation (governing amplitudes ...

UNIRATIONALITY OF CUBIC HYPERSURFACES [PDF]
Journal of the Institute of Mathematics of Jussieu, 2002 Segre proved that a smooth cubic surface over Q is unirational iff it has a rational point. We prove that the result also holds for cubic hypersurfaces over any field, including finite fields.

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 ...
