The class is an introduction to equivariant stable homotopy theory for finite groups of equivariance; we will use orthogonal G-spectra as our model. Some topics to be covered include: equivariant stable homotopy groups, the `genuine' G-equivariant stable homotopy category, the Wirthmüller isomorphism, transfers, genuine and geometric fixed points, and the tom Dieck splitting. Along the way, we'll discuss many examples.
