Ilkyoo Choi (최일규), Flexibility of Planar Graphs
Room B232 IBS (기초과학연구원)Oftentimes in chromatic graph theory, precoloring techniques are utilized in order to obtain the desired coloring result. For example, Thomassen's proof for 5-choosability of planar graphs actually shows that two adjacent …

Eun Jung Kim (김은정), Solving hard cut problems via flow-augmentation
Room B232 IBS (기초과학연구원)We present a new technique for designing fixed-parameter algorithms for graph cut problems in undirected graphs, which we call flow augmentation. Our technique is applicable to problems that can be …
Akanksha Agrawal, Polynomial Kernel for Interval Vertex Deletion
Zoom ID: 869 4632 6610 (ibsdimag)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 …
