I will be reporting on the very important paper of Ed Morehouse, "Burritos for the hungry mathematician", in which a burrito is defined precisely as a strong monad in the category of food.

We prove, in this joint work with Maksym Radziwill, a 1978 conjecture of S. Patterson (conditional on the Generalised Riemann hypothesis)
concerning the bias of cubic Gauss sums.
This explains a well-known numerical bias in the distribution of cubic Gauss sums first observed…

The classical Erdos–Littlewood–Offord theorem says that for any n nonzero vectors in R^d, a random signed sum concentrates on any point with probability at most O(n^{1/2}). Combining tools from probability theory, additive combinatorics, and model theory, we obtain an anti-concentration…

Given a grid diagram for a knot or link K in S^3, we construct a spectrum whose homology is the knot Floer homology of K. We conjecture that the homotopy type of the spectrum is an invariant of K. Our construction does not use holomorphic geometry, but rather builds on the…

Weak solution concepts for mean curvature flow have been investigated since the seminal work of Brakke in the 70’s. We propose a new weak solution concept for (two-phase) mean curvature flow which enjoys both (unconditional) existence and (weak-strong) uniqueness properties. These solutions are…

Yuval Wigderson (Stanford)

Puccini's opera Turandot centers on three riddles, which the prince Calaf must answer correctly in order to avoid death. This talk won't be about opera, but it will feature three riddles in Ramsey theory: classical Ramsey numbers, Ramsey numbers of books, and Ramsey multiplicity constants.…
