The Morava K-theory analogue of Yagita's conjecture

At least 1 year old · documented by

Let KK be a compact connected Lie group, TT its maximal torus, and π ⁣:K→K/T\pi\colon K\rightarrow K/T the natural projection. Denote by G=KCG=K_{\mathbb C} the corresponding split reductive group over C\mathbb C. For A=K(n)A=\mathrm K(n) or A=CK(n)A=\mathrm{CK}(n), consider the algebraic theory A∗(G)A^*(G) and the topological theory Atop∗(K/T)A^*_{\mathrm{top}}(K/T). The Morava K-theory analogue of Yagita's conjecture. One has

A∗(G)≅π∗(Atop∗(K/T)).A^*(G)\cong\pi^*\big(A^*_{\mathrm{top}}(K/T)\big).

This is presented as the analogue, for Morava K-theory and connective Morava K-theory, of Yagita's conjectural comparison between algebraic and topological cobordism. The supplied text does not state whether this claim is proved or remains open.
