Multiplicative rule in the Grothendieck cohomology of a flag variety

Haibao Duan

In the Grothendieck cohomology of a flag variety G/H there are two canonical additive bases, namely, the Demazure basis and the Grothendieck basis We present explicit formulae that…

Non-zero degree maps between $2 n$ -manifolds

Haibao Duan, Shicheng Wang

Thom-Pontrjagin constructions are used to give a computable necessary and sufficient condition when a homomorphism $ϕ : H^{n} (L; Z) \to H^{n} (M; Z)$ can be realized by a map $f : M \to L$ of…
