معرفی
Takuya Sakasai is an Associate Professor in the Department of Global Geometry at the Graduate School of Mathematical Sciences, The University of Tokyo. His research focuses on topology, particularly mapping class groups of surfaces, characteristic classes of bundles, and 3-dimensional topology.
Education: He completed his doctoral dissertation titled "Mapping class groups, groups of homology cobordisms of surfaces and invariants of 3-manifolds" at The University of Tokyo in 2006.
Research Interests: His work centers on the mapping class group of surfaces, exploring its connections to various fields such as topology, geometry, algebra, complex analysis, and mathematical physics. He investigates the cohomology rings of these groups as characteristic classes of surface bundles and their implications for the moduli space of Riemann surfaces. Additionally, he studies infinite-dimensional Lie algebras related to these structures and constructs new invariants for knots and 3-manifolds using noncommutative algebra.
Scientific Awards: In 2007, he received the Takebe Katahiro Encouragement Award from the Mathematical Society of Japan.
Workshops and Conferences: He has organized and participated in numerous international workshops, including the "Johnson homomorphisms and related topics" series (2013, 2017, 2019), the "Braids, Configuration Spaces and Quantum Topology" workshop (2015), and the "Topology and Computer" workshops (2013, 2014).
