Nariya KAWAZUMI

Nariya Kawazumi is a Professor at the Department of Mathematical Sciences, Graduate School of Mathematical Sciences, University of Tokyo. His research focuses on topology and Riemann surfaces, particularly the cohomology of moduli spaces and automorphism groups of free groups. He utilizes twisted cocycles and canonical differential forms to explore these structures.

• Keywords: Riemann surface, mapping class group, Magnus expansion, hyperelliptic mapping class group
