Idea

The model structure for dendroidal left fibrations is an operadic analog of the model structure for left fibrations. Its fibrant objects over Assoc are A-∞ spaces, over Comm they are E-∞ spaces.

Properties

Proposition

For f:STf : S \to T any morphism of dendroidal sets, the induced adjunction (by Kan extension)

(f !f *):dSet/Tf *f !dSet/S (f_! \dashv f^* ) : dSet/T \stackrel{\overset{f_!}{\leftarrow}}{\underset{f^*}{\to}} dSet/S

is a Quillen adjunction for the corresponding model structures for dendroidal left fibrations over SS and TT. It is a Quillen equivalence if ff is a weak equivalences in the Cisinki-Moerdijk model structure on dendroidal sets.

This is (Heuts, prop. 2.4).
