Due to COVID-19, the organizers decided to postpone the conference “Seymour is Seventy” to be held in Lyon, France, June 15-19, 2020. We hope to run a similar event in the summer of 2021 instead. Specific decisions on the dates are to be made when the situation clarifies.

Eun-Kyung Cho (조은경) gave a talk on the problem of decomposing a graph into a d-degenerate graph and a graph of bounded maximum degree at the Discrete Math Seminar

On March 3, 2020, Eun-Kyung Cho (조은경) from Hankuk University of Foreign Studies presented a talk on the existence of a decomposition of a planar graph into two edge-disjoint subgraphs, one of which is d-degenerate and the other has maximum degree at most h at the discrete math seminar. The title of her talk was “Decomposition of a planar graph into a d-degenerate graph and a graph with maximum degree at most h“. She will visit the IBS discrete math group until March 6.

Xin Zhang (张欣) gave a talk on the problem of partitioning a graph into forests of the almost equal size at the Discrete Math Seminar

On February 25, 2020, Xin Zhang (张欣) from Xidian University, China gave a talk on the problem of equitable tree-k-coloring of graphs and its variations. The title of his talk is “On the equitable tree-coloring of graphs with low degeneracy“. He is currently visiting the IBS discrete mathematics group for 1 year until August 2020 for his sabbatical leave.
