Galois groups of simple abelian varieties over finite fields and exceptional Tate classes

Santiago Arango-Piñeros, Sam Frengley, Sameera Vemulapalli

We prove new cases of the Tate conjecture for abelian varieties over finite fields, extending previous results of Dupuy--Kedlaya--Zureick-Brown, Lenstra--Zarhin, Tankeev, and Zarhi…

Brill--Noether theory of smooth curves in the plane and on Hirzebruch surfaces

Hannah Larson, Sameera Vemulapalli

In this paper, we describe the Brill--Noether theory of a general smooth plane curve and a general curve $C$ on a Hirzebruch surface of fixed class. It is natural to study the line…

Sumsets of sequences in abelian groups and flags in field extensions

Sameera Vemulapalli

For a finite abelian group $G$ with subsets $A$ and $B$ , the sumset $A B$ is ${ab ∣ a \in A, b \in B}$ . A fundamental problem in additive combinatorics is to find a lower bound…
