Yagita's conjecture. The restriction map $\Omega^*(E/P)\to\Omega^*(G/P)$ is injective. This conjecture is an algebraic-cobordism form of a question originally stated for Brown--Pet…

Let $k$ be a field, let $\Omega^{\ast}(k)$ denote algebraic cobordism of $k$, and let $\mathbb{L}^{\ast}$ denote the Lazard ring. In characteristic zero, there is an isomorphism…

Bressler–Evens conjecture. The discovery of this failure of independence deterred further development of the Demazure–Kostant–Kumar line of ideas until work in which the non-indepe…
