A Fulton-Hansen theorem for almost homogeneous spaces

János Kollár, Aaron Landesman

We prove a generalization of the Fulton-Hansen connectedness theorem, where $P^{n}$ is replaced by a normal variety on which an algebraic group acts with a dense orbit.

A Lefschetz theorem for intersections with projective varieties

Aaron Landesman

One version of the classical Lefschetz hyperplane theorem states that for $U \subset P^{n}$ a smooth quasi-projective variety of dimension at least $2$ , and $H \cap U$ a gene…

Invariance of the tame fundamental group under base change between algebraically closed fields

Aaron Landesman

We show that the tame étale fundamental group of a connected normal finite type separated scheme remains invariant upon base change between algebraically closed fields of character…

The geometric distribution of Selmer groups of elliptic curves over function fields

Tony Feng, Aaron Landesman, Eric M. Rains

Fix a positive integer $n$ and a finite field $F_{q}$ . We study the joint distribution of the rank of $E$ , the $n$ -Selmer group of $E$ , and the $n$ -torsion in the Tate-Shafar…
