Divided power algebras and distributive laws

Abstract: We study the divided power structures over a product of operads with distributive law. We give a systematic method to characterise the divided power algebras over such a product from the structures of divided power algebra coming from each of the the factor operads. We characterise divided power algebras with operadic derivation, as well as divided power $p$-level algebras in characteristic $p$, and divided power Poisson algebras in characteristic 3.
