| Outline of Final Research Achievements |
We studied a generalization of the Gysin formulas for the Hall-Littlewood polynomials due to Pragacz to the complex-oriented generalized cohomology theory. We introduced the universal Hall-Littlewood functions, and established the universal Gysin formulas for them. We also studied a generalization of the Darondeau-Pragacz formulas in the ordinary cohomology theory to the complex cobordism theory, and extended their formulas in the case of type A flag bundles. In the course of our study, we introduced the universal factorial Hall-Littlewood P- and Q-functions, and were able to obtain the generating functions for them as a by-product of our formulas.
