Monogamy of entanglement and convex geometry
CMSA 20 Garden Street, Cambridge, MA, United StatesSpeaker: Aram Harrow (MIT) Title: Monogamy of entanglement and convex geometry Abstract: The SoS (sum of squares) hierarchy is a flexible algorithm that can be used to optimize polynomials and to test whether a quantum state is entangled or separable. (Remarkably, these two problems are nearly isomorphic.) These questions lie at the boundary of P, NP and the unique games […]
Compactification for cluster varieties without frozen variables of finite type
Speaker: Man-Wai Cheung Title: Compactification for cluster varieties without frozen variables of finite type Abstract: Cluster varieties are blow up of toric varieties. They come in pairs $(A,X)$, with $A$ and $X$ built from dual tori. Compactifications of $A$, studied by Gross, Hacking, Keel, and Kontsevich, generalize the polytope construction of toric varieties while […]
