The Mahowald-lift existence conjecture for equivariant self-maps

Suppose that XSp(2),ωC2X\in\mathrm{Sp}^{C_2}_{(2),\omega} is a type (n,n1)(n,n-1) complex. Suppose further that the modified inductive procedure produces a vnv_n-self map as a Mahowald invariant of an iterate vjv^j of a vn1v_{n-1}-self map on XΦC2X^{\Phi C_2}. Mahowald-lift existence conjecture. A power jj satisfying these criteria always exists. If so, the corresponding Mahowald lift is a v(n,n1)v_{(n,n-1)}-self map and its cofiber has type (n+1,n)(n+1,n). The assertion is presented as part of a proposed strategy for inductively constructing equivariant periodic self-maps; no resolution is supplied in the given text.
