| Outline of Final Research Achievements |
(1)Using the universal formal group law in complex cobordism theory, we introduced a new family of symmetric functions, which is a generalization of the usual factorial Schur P- and Q-functions due to Ivanov. Using these symmetric functions, we gave a description of the complex oriented generalized (co)homology Hopf algebras of the loop spaces on the infinite symplectic and special orthogonal group. Furthermore, we showed the various properties of these functions such as factorization property, vanishing property, and basis theorem.
(2)We also introduced a generalization of the usual factorial Schur functions. We gave a characterization of these symmetric functions via the Gysin homomorphism for the flag bundle associated with a complex vector bundle in complex oriented generalized cohomology theory.
