Résumé : E-infinity ring spectra are a topological version of `derived commutative rings'. It is well known that their homotopy theory contains lots of very interesting stable homotopy phenomena. In this talk I will discuss some very simple examples built using 2-primary Hopf invariant 1 elements which lead to some interesting results and problems about connective K-theory and topological modular forms.
