nLab equivariant formal group




A generalization of the concept of formal groups to a situation where an additional equivariance group acts.

In generalization of how formal groups correspond to complex oriented cohomology theories so equivariant formal groups correspond to equivariant complex oriented cohomology theories.


Universal equivariant formal group

Greenlees shows (Greenlees 01a, Greenlees 01b, Theorem 13.1 ) that the coefficient ring of equivariant complex cobordism theory classifies equivariant formal group laws over Noetherian rings, but the general conjecture is still open.
