An algebro-geometric model for the configuration category
Pedro Boavida de Brito, Geoffroy Horel, Danica Kosanović
Using log-geometry, we construct a model for the configuration category of a smooth algebraic variety. As an application, we prove the formality of certain configuration spaces.
An operadic proof of the BTT Theorem
Joana Cirici, Geoffroy Horel
In this note, we explain an operadic proof of the BTT Theorem stating that the deformation theory of Calabi-Yau varieties is unobstructed. We also provide a short new proof of the…
E2 formality via obstruction theory
Geoffroy Horel
We attack the question of E_2-formality of differential graded algebras over prime fields via obstruction theory. We are able to prove that E_2-algebras whose cohomology ring is a…
Weight structures and formality
Coline Emprin, Geoffroy Horel
This is a survey on formality results relying on weight structures. A weight structure is a naturally occurring grading on certain differential graded algebras. If this weight sati…
Automorphisms of framed operads
Geoffroy Horel, Thomas Willwacher
Let be an operad acted upon by a group , and let be the corresponding framed operad. We relate the homotopy automorphism groups of $\m…
