Concentration on HDX: Derandomization Beyond Chernoff
10:30am|Simonyi 101 and Remote Access

Chernoff's bound states that for any $A \subset [N]$ the probability a random $k$-tuple $s \in {[N] \choose k}$ correctly `samples' $A$ (i.e. that the density of $A$ in $s$ is close to its mean) decays exponentially in the dimension $k$. In 1987...

Selmer Ranks for Some Four-Dimensional Symplectic Galois Representations, in the Spirit of Bipartite Euler Systems
Naomi Sweeting
3:40pm|322 Fine Hall

I will describe a new bipartite Euler system-type construction system for GSp_4 and its inner forms, based on the special cycles appearing in the Kudla program (for instance, Shimura curves on Siegel threefolds). This leads to new results towards...
