Abstract
As a generalization of the ring spectrum of topological modular forms, we construct a graded ring spectrum of topological Jacobi forms, . This is constructed as the global sections of a sheaf of -ring spectra on the stacky universal elliptic curve using circle-equivariant . Complete calculations of its homotopy at odd primes and partial results at are given.
