چکیده
We show that the BRST Lagrangian double copy construction of $\mathcal{N}=0$ supergravity as `square' Yang-Mills theory finds a natural interpretation in terms homotopy algebras. significantly expand on our previous work arguing validity at loop level, and we give detailed derivation copied operator. Our constructions are very general can be applied to vast set examples.

Homotopy Dg Algebras Induce Homotopy Bv Algebras
Let TA denote the space underlying the tensor algebra of a vector space A. In this short note, we show that if A is a differential graded algebra, then TA is a differential BatalinVilkovisky algebra. Moreover, if A is an A∞ algebra, then TA is a commutative BV∞ algebra. 1. Main Statement Let (A, dA) be a complex over a commutative ring R. Our convention is that dA is of degree +1. The space TA ...
متن کاملHomotopy Theory of Homotopy Algebras
The goal of this paper is to study the homotopy theory of homotopy algebras over a Koszul operad with their infinity morphisms. The method consists in endowing the category of coalgebras over the Koszul dual cooperad with a model category structure. CONTENTS Introduction 1 1. Recollections 2 2. Model category structure for coalgebras 5 3. Conclusion 14 Appendix A. A technical lemma 15 Reference...
متن کاملDerivations of Homotopy Algebras
We recall the definition of strong homotopy derivations of A∞ algebras and introduce the corresponding definition for L∞ algebras. We define strong homotopy inner derivations for both algebras and exhibit explicit examples of both.
متن کاملHomotopy Algebras for Operads
We present a definition of homotopy algebra for an operad, and explore its consequences. The paper should be accessible to topologists, category theorists, and anyone acquainted with operads. After a review of operads and monoidal categories, the definition of homotopy algebra is given. Specifically, suppose that M is a monoidal category in which it makes sense to talk about algebras for some o...
متن کاملFree Homotopy Algebras
An explicit description of free strongly homotopy associative and free strongly homotopy Lie algebras is given. A variant of the Poincaré-Birkhoff-Witt theorem for the universal enveloping A(m)-algebra of a strongly homotopy Lie algebra is formulated. Introduction This note was originated many years ago as my reaction to questions of several people how free strongly homotopy algebras can be des...
