A recognition principle for iterated suspensions as coalgebras over the little cubes operad

Oisín Flynn-Connolly, José M. Moreno-Fernández, Felix Wierstra

Our main result is a recognition principle for iterated suspensions as coalgebras over the little disks operads. Given a topological operad, we construct a comonad in pointed topol…

On the homotopy fixed points of Maurer-Cartan spaces with finite group actions

José M. Moreno-Fernández, Felix Wierstra

We develop the basic theory of Maurer-Cartan simplicial sets associated to (shifted complete) algebras equipped with the action of a finite group. Our main result assert…

A spectral sequence for tangent cohomology of algebras over algebraic operads

José Moreno-Fernández, Pedro Tamaroff

Operadic tangent cohomology generalizes the existing cohomology theories of Chevalley--Eilenberg, Hochschild, and Harrison to address the deformation theory of general types of alg…

Iterated suspensions are coalgebras over the little disks operad

José M. Moreno-Fernández, Felix Wierstra

We study the Eckmann-Hilton dual of the little disks algebra structure on iterated loop spaces: With the right definitions, every -fold suspension is a coalgebra over the little…

Formality criteria in terms of higher Whitehead brackets

Urtzi Buijs, José M. Moreno-Fernández

We provide two criteria for discarding the formality of a differential graded Lie algebra in terms of higher Whitehead brackets, which are the Lie analogue of the Massey products o…

A-infinity structures and Massey products

Urtzi Buijs, José Manuel Moreno-Fernández, Aniceto Murillo

We show how and when it is possible to detect and recover higher Massey products on the cohomology of a differential graded algebra with higher multiplications on quasi-iso…
