Jeck Lim, Sums of linear transformations

Zoom ID: 870 0312 9412 (ibsecopro)

We show that if $L_1$ and $L_2$ are linear transformations from $\mathbb{Z}^d$ to $\mathbb{Z}^d$ satisfying certain mild conditions, then, for any finite subset $A$ of $\mathbb{Z}^d$, \ This result corrects

Xizhi Liu, Hypergraph Turán problem: from 1 to ∞

Zoom ID: 870 0312 9412 (ibsecopro)

One interesting difference between (nondegenerate) Graph Turán problem and Hypergraph Turán problem is that the hypergraph families can have at least two very different extremal constructions. In this talk, we

Eric Vigoda, Computational phase transition and MCMC algorithms

Room B332 IBS (기초과학연구원)

This talk will highlight recent results establishing a beautiful computational phase transition for approximate counting/sampling in (binary) undirected graphical models (such as the Ising model or on weighted independent sets). The computational problem is to
