| May 18, 2011 at 13:09 | comment | added | Tom Goodwillie | I don't think that there is any reason why representation spheres have to appear in the foundations of a homotopy theory of $G$-spaces. They occur naturally when you look at $G$-manifolds. For $G$-spectra they are usually built into the definition, and I imagine there is more than good viewpoint as to why they should. | |
