The Learning with Errors (LWE) problem is the fundamental backbone of modern lattice based cryptography. However, schemes based on LWE are often impractical, so Ring LWE was introduced as a form of 'structured' LWE. Another popular variant, Module LWE, generalizes this exchange by implementing a module structure over a Ring LWE instance. In this work, we introduce a novel variant of LWE over cyclic algebras (CLWE), which can be seen as a non-commutative version of Ring LWE. The proposed construction is both more efficient than Module LWE and conjecturally more secure than Ring LWE, the best of both worlds.

Abstract: I will survey some recent vanishing theorems for the mod p cohomology of Shimura varieties. I will mention some p-adic results and some l-adic results, where l is a prime different from p. Both settings rely on the geometry of the Hodge-Tate period morphism, but I will try to highlight the differently flavoured techniques that are needed. This is largely based on joint work with Daniel Gulotta and Christian Johansson, and on separate joint work with Peter Scholze.
Dan York: Make a Fence around the Torah: Re-examining the Woman’s Prescription on the Fruit in Genesis 3:3
The paper re-examines the woman’s prescription on the fruit in Gen 3:3 according to the category of fence-making for the Torah (e.g. m. Avot 1.1). I situate the discussion within the context of early Jewish and Christian literature (e.g. Jubilees, Targums, Ephrem the Syrian, some rabbinic texts, etc.) to reframe the discussion. I, then, bring together Gen 3:3 with Ex 19:12 to attempt to show that the fence that the woman creates can be seen as a positive move in the light of the Sinai narrative.
