The inclusion of a subgroup H into a compact Lie group G induces an adjoint triple of induction, restriction and coinduction functors between the categories of G-spectra and H-spectra, analogous to the functors in representation theory. In many cases, an algebraic model is known for rational G-spectra, in particular, in the case of (co)free G-spectra. In this talk, I will explain how to connect the induction, restriction and coinduction functors in topology with functors in algebra, and focus on the main ingredients used, namely Gorenstein ring spectra and flat model structures.
