Currently, I am receiving a grant of 200 million won (approx 160,000 Euro) for 2018-2022, by the National Research Foundation of Korea. The title is ‘Tight polynomial kernelizations for various graph modification problems”. If you want to visit me, I would like to support you.
Graph theory, Combinatorial Optimization, Structural Graph Theory, Parameterized Complexity.
Some keywords: Tree-width, rank-width, mim-width, vertex-minor, minor, Erdos-Posa, Graph coloring, chi-boundedness, dense graph classes, induced subdivision, polynomial kernelization, holes
FPT news Feb. 2018 : Here is a news paper of fpt community that contains a short article about my recent SODA 2018 paper ‘Erdos-Posa property of chordless cycles and its applications’.
I am one of the members organizing Incheon Combinatorics Seminar. We organize meetings in Thursday (Incheon National University, Inha University) or Friday (SUNY Korea) for this spring semester. We are happy to invite you to give a talk. Please e-mail me if you are interested in.
