Program obfuscation: outside the black box
Omer Paneth
10:30am

This talk will survey recent progress on program obfuscation from feasibility results to applications in cryptography and complexity theory. We will also describe a simple obfuscation construction based on cryptographic multi-linear maps and give a...

16-rank of class groups of quadratic number fields
Djordjo Milovic
4:30pm

We will discuss how Vinogradov's method applies to the study of the 2-part of class groups in certain thin families of quadratic number fields. We will show how the method yields a density result for the 16-rank in the family of quadratic number...

$C^infty$ closing lemma for three-dimensional Reeb flows via embedded contact homology
Kei Irie
10:45am

$C^r$ closing lemma is an important statement in the theory of dynamical systems, which implies that for a $C^r$ generic system the union of periodic orbits is dense in the nonwondering domain. $C^1$ closing lemma is proved in many classes of...
