 The memoir presents a systematic study of rational \(S^1\)equivariant cohomology theories, and a complete algebraic model for them. It provides a classification of such cohomology theories in simple algebraic terms and a practical means of calculation. The power of the model is illustrated by analysis of the Segal conjecture, the behaviour of the AtiyahHirzebruch spectral sequence, the structure of \(S^1\)equivariant \(K\)theory, and the rational behaviour of cyclotomic spectra and the topological cyclic homology construction.
