The Department of Mathematics Education at Seoul National University will host the fifth edition of "SNU international symposium on Mathematics Education" on November 8th, 2025. The symposium features the combinatorics and topology, with emphasis on their role of "connections" interpreted in a broad sense. The symposium will bring together experts in combinatorics and topology and foster insightful discussions and academic exchange. To encourage wide participation, the talks are designed to be highly accessible, making the event an excellent opportunity for undergraduate students, graduate students, and prospective teachers.
