Akanksha Agrawal, Polynomial Kernel for Interval Vertex Deletion
Given a graph G and an integer k, the Interval Vertex Deletion (IVD) problem asks whether there exists a vertex subset S of size at most k, such that G-S is an interval graph. …

June Huh (허준이), Kazhdan-Lusztig polynomials of graphs and matroids
Room B232 IBS (기초과학연구원)I will introduce Kazhdan-Lusztig polynomials of matroids and survey combinatorial and geometric theories built around them. The focus will be on the conjecture of Gedeon, Proudfoot, and Young that all …

Robert Ganian, Solving Integer Linear Programs by Exploiting Variable-Constraint Interactions
Zoom ID: 869 4632 6610 (ibsdimag)Integer Linear Programming (ILP) is among the most successful and general paradigms for solving computationally intractable optimization problems in computer science. ILP is NP-complete, and until recently we have lacked a systematic study …

Yunbum Kook (국윤범), Vertex Sparsification for Edge Connectivity
Room B232 IBS (기초과학연구원)Graph compression or sparsification is a basic information-theoretic and computational question. A major open problem in this research area is whether $(1+\epsilon)$-approximate cut-preserving vertex sparsifiers with size close to the number …

Tuan Tran, Anti-concentration phenomena
Room B232 IBS (기초과학연구원)Let $X$ be a real random variable; a typical anti-concentration inequality asserts that (under certain assumptions) if an interval $I$ has small length, then $\mathbb{P}(X\in I)$ is small, regardless the …
