Coloured Koszul duality and strongly homotopy operads
Pepijn van der Laan
This paper proves Koszul duality for coloured operads and uses it to introduce strongly homotopy operads as a suitable homotopy invariant version of operads. It shows that rational…

Operads and the Hopf algebras of renormalisation
Pepijn van der Laan
Functors from (co)operads to bialgebras relate Hopf algebras that occur in renormalisation to operads, which simplifies the proof of the Hopf algebra axioms, and induces a characte…
