Non abelian cohomology of extensions of Lie algebras as Deligne groupoid
Yael Fregier
In this note we show that the theory of non abelian extensions of a Lie algebra by a Lie algebra can be understood in terms of a differential graded L…

Homotopy moment maps
Martin Callies, Yael Fregier, Christopher L. Rogers +1
Associated to any manifold equipped with a closed form of degree >1 is an `L-infinity algebra of observables' which acts as a higher/homotopy analog of the Poisson algebra of funct…

Simultaneous deformations of algebras and morphisms via derived brackets
Yael Fregier, Marco Zambon
We present a method to construct explicitly L-infinity algebras governing simultaneous deformations of various kinds of algebraic structures and of their morphisms. It is an altern…
