On the γ-filtration of oriented cohomology of complete spin-flags
Changlong Zhong
We study the characteristic map of algebraic oriented cohomology of complete spin-flags and the ideal of invariants of formal group algebra. As an application, we provide an annihi…
A coproduct structure on the formal affine Demazure algebra
Baptiste Calmès, Kirill Zainoulline, Changlong Zhong
In the present paper we generalize the coproduct structure on nil Hecke rings introduced and studied by Kostant-Kumar to the context of an arbitrary algebraic oriented cohomology t…
Invariants, exponents and formal group laws
Jose Malagon-Lopez, Kirill Zainoulline, Changlong Zhong
Let W be the Weyl group of a crystallographic root system acting on the associated weight lattice by reflections. In the present notes we extend the notion of an exponent of the W-…
Erratum: On the torsion of Chow groups of twisted Spin-flags
Sanghoon Baek, Kirill Zainoulline, Changlong Zhong
In the erratum we correct a mistake (due to a wrong choice of basic polynomial invariants over Z[1/2]) in the original paper (v1). Using the correct basic polynomial invariants we…
