Rationality, universal generation and the integral hodge conjecture

, 2019
We use the universal generation of algebraic cycles to relate (stable) rationality to the integral Hodge conjecture. We show that the Chow group of 1–cycles on a cubic hypersurface is universally generated by lines.

Chow hypersurfaces and realizability problems in tropical geometry. [PDF]

Tropical geometry is an area of mathematics between algebraic geometry, polyhedral geometry and combinatorics. The basic principle of tropical geometry is to associate to an algebraic variety X a polyhedral complex Trop(X) called the tropicalization of X.

The gonality theorem of noether for hypersurfaces

, 2013
It is well known since Noether that the gonality of a smooth curve C C P2 of degree d ≥ 4 is d - 1. Given a k-dimensional complex projective variety X, the most natural extension of gonality is probably the degree of irrationality, that is, the minimum ...

Ricci curvature of real hypersurfaces in complex hyperbolic space [PDF]

, 2002
summary:First we prove a general algebraic lemma. By applying the algebraic lemma we establish a general inequality involving the Ricci curvature of an arbitrary real hypersurface in a complex hyperbolic space.
