On December 13, 2024, Jun Gao (高峻) from the IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar on the maximum sum of the p-th power of degrees in a hypergraph without fixed subhypergraphs. The title of his talk is “Phase transition of degenerate Turán problems in p-norms“.

For a positive real number
We also prove a general upper bound that is tight up to a

On August 30, 2022, Jun Gao (高峻) from the IBS Extremal Combinatorics and Probability Group gave a talk at the Discrete Math Seminar about the tight upper bound on the number of (k-1)-cliques in a k-critical graph, solving the conjecture of Abbott and Zhou in 1992. The title of his talk was “Number of (k-1)-cliques in k-critical graph“.

Welcome Jun Gao, a new member of the IBS Extremal Combinatorics and Probability Group
The IBS Discrete Mathematics Group welcomes Dr. Jun Gao (高峻), a new (and second) research fellow at the IBS Extremal Combinatorics and Probability Group from August 1, 2022. He received his Ph.D. from the University of Science and Technology of China (USTC) under the supervision of Prof. Jie Ma.
