Mathematics (Topology, Knot Theory)


Hiroshima University, Graduate School of Advanced Science and Engineering, Mathematics, Associate Professor/ RIKEN, Interdisciplinary Theoretical and Mathematical Sciences Program, Visiting Scientist



Based on combinatorial methods and algebraic methods, Kotorii studies knot theory in topology. In particular, she focused on link invariants and the classification of links by applying local deformation theory. Kotorii elucidated the properties of invariants including higher-order linking numbers and generalized them. Furthermore, she figured out the classification for link-homotopy. Kotorii has advanced interdisciplinary research involving topology with knot theory.
