On May 20, 2019, Lars Jaffke from University of Bergen, Norway presented his work on algorithmic questions regarding the b-chromatic number of graphs at the Discrete Math Seminar. The title of his talk was “A complexity dichotomy for critical values of the b-chromatic number of graphs“.
On May 16, 2019, Xin Zhang (张欣) from Xidian University, China discusses various results on the equitable tree-k-coloring of graphs, a problem of partitioning the vertex set of a graph into vertex-disjoint induced subgraphs having no cycles with almost same size. The title of his talk was “On equitable tree-colorings of graphs“. Xin Zhang is visiting IBS Discrete Mathematics Group from May 15 to May 19.
Sang June Lee (이상준) from Duksung Women’s University presented his recent work on the strong Sidon sets at the Discrete Math Seminar on May 8, 2019. The title of his talk was “On strong Sidon sets of integers“.
Rose McCarty from University of Waterloo presented her recent breakthrough on the polynomially 𝜒-boundedness of circle graphs at the Discrete Math Seminar on April 26, 2019 . The title of her talk was “circle graphs are polynomially chi-bounded.”
Sang-il Oum delivered the plenary lecture at the 2019 Korean Mathematical Society Spring Meeting (대한수학회 봄 연구발표회) held at the Kangwon National University in Chuncheon on April 19-20, 2019. The title of his talk was “How to decompose a graph into a tree-like structure”.
Jon-Lark Kim (김종락) from Sogang University presented a talk at Discrete Math Seminar on April 18, 2019. The title of his talk was “Introduction to Boolean functions with Artificial Neural Network“.
