This talk is about joint work with Nancy Hingston and Alexandru Oancea. We describe various secondary coproducts on the Floer homology of a cotangent bundle and show that, under Viterbo's isomorphism, they all correspond to the Goresky-Hingston coproduct on loop space homology. The proof uses compactified moduli spaces of punctured holomorphic annuli.
