    I have started rational equivariant stable homotopy theory, but so far there is nothing but references.

    I see they’re pushing on to SO(3), as mentioned in Rational SO(2)-Equivariant Spectra

    M. Kedziorek. An algebraic model for rational SO(3) - spectra. In preparation.

    Thanks for the pointer! Apparently this is a thesis which is out be now, see here. Am adding it to the entry now.

    What I am actually after is equivariance with respect to finite subgroups of SO(3). But of course some of them factor through the inclusion O(2)SO(3), the cyclic groups and the dihedral groups. Moreover, I am after seeing whether the quaternionic Hopf fibration with its canonical action by SO(3) becomes a non-torsion element for any of these subgroups, in the corresponding RO(G)-degree 3. If that works for the cyclic groups of the dihedral groups, then it will be visible already in just SO(2)-equivariant homotopy theory.

    I added that first item mentioned in #2:

    It only came out last week.

    Thanks. And I just fixed a typo in #3: of course the Dihedral group sits in O(2)SO(3), not in SO(2).
