M. Kontsevich's graph complex and the Grothendieck–Teichmüller Lie algebra

T Willwacher - Inventiones mathematicae, 2015 - Springer
We show that the zeroth cohomology of M. Kontsevich's graph complex is isomorphic to the
Grothendieck–Teichmüller Lie algebra grt _1 grt 1. The map is explicitly described. This …

The rational homotopy of mapping spaces of E operads

B Fresse, V Turchin, T Willwacher - arXiv preprint arXiv:1703.06123, 2017 - arxiv.org
We express the rational homotopy type of the mapping spaces $\mathrm {Map}^ h (\mathsf
D_m,\mathsf D_n^{\mathbb Q}) $ of the little discs operads in terms of graph complexes …

[HTML][HTML] A version of the Goldman–Millson theorem for filtered L∞-algebras

VA Dolgushev, CL Rogers - Journal of Algebra, 2015 - Elsevier
In this paper we consider L∞-algebras equipped with complete descending filtrations. We
prove that, under some mild conditions, an L∞ quasi-isomorphism U: L→ L˜ induces a weak …

Differentials on graph complexes

A Khoroshkin, T Willwacher, M Živković - Advances in Mathematics, 2017 - Elsevier
We study the cohomology of complexes of ordinary (non-decorated) graphs, introduced by
M. Kontsevich. We construct spectral sequences converging to zero whose first page …

Maurer-Cartan methods in deformation theory: the twisting procedure

V Dotsenko, S Shadrin, B Vallette - arXiv preprint arXiv:2212.11323, 2022 - arxiv.org
This monograph provides an overview on the Maurer-Cartan methods in algebra, geometry,
topology, and mathematical physics. It offers a conceptual, exhaustive and gentle treatment …

A model for configuration spaces of points

R Campos, T Willwacher - Algebraic & Geometric Topology, 2023 - msp.org
We construct a real combinatorial model for the configuration spaces of points of compact
smooth oriented manifolds without boundary. We use these models to show that the real …

The intrinsic formality of En-operads

B Fresse, T Willwacher - J. Eur. Math. Soc, 2020 - ems.press
We establish that En-operads satisfy a rational intrinsic formality theorem for n≥ 3. We get
our results in the category of Hopf cooperads in cochain graded dg-modules which defines a …

The Lambrechts–Stanley model of configuration spaces

N Idrissi - Inventiones mathematicae, 2019 - Springer
We prove the validity over RR of a commutative differential graded algebra model of
configuration spaces for simply connected closed smooth manifolds, answering a conjecture …

[HTML][HTML] What do homotopy algebras form?

VA Dolgushev, AE Hoffnung, CL Rogers - Advances in Mathematics, 2015 - Elsevier
Abstract In paper [4], we constructed a symmetric monoidal category S Lie∞ MC whose
objects are shifted (and filtered) L∞-algebras. Here, we fix a cooperad C and show that …

V Dotsenko, S Shadrin, B Vallette - 2023 - books.google.com
Covering an exceptional range of topics, this text provides a unique overview of the Maurer-
Cartan methods in algebra, geometry, topology, and mathematical physics. It offers a new …
