Abstract

Let GG be a cyclic pp-group or generalized quaternion group, Xπ0SGX\in \pi_0 S_G be a virtual GG-set, and VV be a fixed point free complex GG-representation. Under conditions depending on the sizes of GG, XX, and VV, we construct a self map v ⁣:ΣVC(X)(p)C(X)(p)v\colon\Sigma^V C(X)_{(p)}\rightarrow C(X)_{(p)} on the cofiber of XX which induces an equivalence in GG-equivariant KK-theory. These are transchromatic v1,0v_{1,\vec{0}}-self maps, in the sense that they are lifts of classical v1v_1-self maps for which the telescope C(X)(p)[v1]C(X)_{(p)}[v^{-1}] can have nonzero rational geometric fixed points.
