On November 7, 2023, Bruce A. Reed from the Academia Sinica, Taiwan gave a talk at the Discrete Math Seminar on the existence of every k-vertex tree as a minor in a graph with certain lower bounds on the minimum degree and the maximum degree. The title of his talk was “Some Variants of the Erdős-Sós Conjecture“.
From November 1 to November 5, 2023, the 3rd East Asia Workshop on Extremal and Structural Graph Theory was held in Okinawa, Japan. It is a workshop to bring active researchers in the field of extremal and structural graph theory, especially in East Asia such as China, Japan, and Korea. Participants have a great chance to discuss recent progress in graph theory, interesting open problems, and finding new potential collaborators. The previous workshops were held in Shanghai (2018) and Jeju (2019). The IBS Discrete Mathematics Group was the main sponsor of the workshop.
