Outline of Final Research Achievements

In this research, from algebraic, geometric and combinatorial view points, we generalize the usual cohomology theoretic symmetric functions which appear in Schubert calculus to equivariant K-theory. Furthermore we consider analogous objects in generalized cohomology theory and complex reflection group setting and study the relations via their generating functions. Another achievement is a generalization of hook formula. From these results, we get new perspectives on algebra, geometry and combinatorics.

Academic Significance and Societal Importance of the Research Achievements

これまで、シューベルト・カルキュラスの分野は日本ではあまり研究が進められていなかった。この研究の成果により、同変シューベルト・カルキュラスが強力な新しい研究手法であることが裏付けられることになった。幾何学におけるさらに新たな手法と融合して、今後のこの研究分野の進展が大いに期待できるものとなったと考えられる。
