This involves resolving the operad obtained from $$\mathcal {P}$$ by adding a generator with "derivation relations". For a wide class of Koszul operads $$\mathcal {P}$$ , in particular $$\mathcal {A}{ss}$$ and $$\mathcal {L}{ie}$$ , we describe the strong homotopy derivations by coderivations and show that they are closed under the Lie bracket. We show that symmetrization of a strong homotopy derivation of an $$A_\infty $$ algebra yields a strong homotopy derivation of the symmetrized $$L_\infty $$ algebra. We give examples of strong homotopy derivations generalizing inner derivations.}, number={3}, journal={JOURNAL OF HOMOTOPY AND RELATED STRUCTURES}, author={Doubek, Martin and Lada, Tom}, year={2016}, month={Sep}, pages={599–630} } @article{allocca_lada_2010, title={A finite dimensional A(infinity) algebra example}, volume={17}, number={1}, journal={Georgian Mathematical Journal}, author={Allocca, M.

As an application, symmetric braces are used to describe transfers of strongly homotopy structures.

A significant generalization is required when “gauge parameters” act in a field dependent way. Such symmetries appear in several field theories, most notably in a “Poisson induced” class due to Schaller and Strobl [SS94] and to Ikeda [Ike94], and employed by Cattaneo and Felder [CF99] to implement Kontsevich's deformation quantization [Kon97]. Consideration of “particles of spin > 2” led Berends, Burgers and van Dam [Bur85,BBvD84,BBvD85] to study “field dependent parameters” in a setting permitting an analysis in terms of smooth functions. Having recognized the resulting structure as that of an sh-Lie algebra (L ∞-algebra), we have now formulated such structures entirely algebraically and applied it to a more general class of theories with field dependent symmetries.}, number={1}, journal={COMMUNICATIONS IN MATHEMATICAL PHYSICS}, author={Fulp, R and Lada, T and Stasheff, J}, year={2002}, month={Nov}, pages={25–43} } @article{barnich_fulp_lada_stasheff_2000, title={Algebra structures on Hom (C, L)}, volume={28}, ISSN={["0092-7872"]}, DOI={10.1080/00927870008827169}, abstractNote={We consider the space of linear maps from a coassociative coalgebra C into a Lie algebra L.

It is applied to the space of local functionals equipped with a Poisson bracket, induced by a bracket for local functions along the lines suggested by Gel'fand, Dickey and Dorfman. In this way, higher order maps are constructed which combine to form an sh Lie algebra on the graded differential algebra of horizontal forms. The same construction applies for graded brackets in field theory such as the Batalin-Fradkin-Vilkovisky bracket of the Hamiltonian BRST theory or the Batalin-Vilkovisky antibracket.}, number={3}, journal={COMMUNICATIONS IN MATHEMATICAL PHYSICS}, author={Barnich, G and Fulp, R and Lada, T and Stasheff, J}, year={1998}, month={Feb}, pages={585–601} }
