Abstract

Given two Lie \infty-algebras EE and VV, any Lie \infty-action of EE on VV defines a Lie \infty-algebra structure on EVE\oplus V. Some compatibility between the action and the Lie \infty-structure on VV is needed to obtain a particular Loday \infty-algebra, the non-abelian hemisemidirect product. These are the coherent actions. For coherent actions it is possible to define non-abelian homotopy embedding tensors as Maurer-Cartan elements of a convenient Lie \infty-algebra. Generalizing the classical case, we see that a non-abelian homotopy embedding tensor defines a Loday \infty-structure on VV and is a morphism between this new Loday \infty-algebra and EE.
