Xuding Zhu gave a talk on the list version of the 1-2-3 conjecture and the usage of Combinatorial Nullstellensatz at the Discrete Math Seminar

On July 10, 2023, Xuding Zhu from Zhejiang Normal University gave a talk at the Discrete Math Seminar on the 1-2-3 conjecture of Karoński, Łuczak, and Thomason, its list version by Bartnicki, Grytczuk, and Niwczyk, and the usage of Combinatorial Nullstellensatz. The title of his talk was “List version of 1-2-3 conjecture.”

Tuan Tran gave a talk on a Sauer-Shelah-type lemma in the study of the maximal pattern entropy of a theoretical dynamical system at the Discrete Math Seminar

On July 4, 2023, Tuan Tran from the University of Science and Technology of China gave a talk on a Sauer-Shelah-type lemma in the study of the maximal pattern entropy of a theoretical dynamical system and its connection to a recent result in communication complexity at the Discrete Math Seminar. The title of his talk was “Complexity of null dynamical systems.”

Suyun Jiang (江素云) gave a talk on the maximum number of edges in a connected graph without a fixed tree at the Discrete Math Seminar

On May 30, 2023, Suyun Jiang (江素云) from Jianghan University gave a talk on the maximum number of edges in a connected graph without a fixed tree at the Discrete Math Seminar. She is currently a visiting scholar at the IBS Extremal Combinatorics and Probability Group. The title of her talk was “How connectivity affects the extremal number of trees.”
