Props of ribbon graphs, involutive Lie bialgebras and moduli spaces of curves M_g,n

  title={Props of ribbon graphs, involutive Lie bialgebras and moduli spaces of curves M\_g,n},
  author={Sergei A. Merkulov and Thomas Willwacher},
  journal={arXiv: Quantum Algebra},
We establish a new and surprisingly strong link between two previously unrelated theories: the theory of moduli spaces of curves Mg,n (which, according to Penner, is controlled by the ribbon graph complex) and the homotopy theory of Ed operads (controlled by ordinary graph complexes with no ribbon structure, introduced first by Kontsevich). The link between the two goes through a new intermediate stable ribbon graph complex which has roots in the deformation theory of quantum A∞ algebras and…

Oriented hairy graphs and moduli spaces of curves

We discuss a graph complex formed by directed acyclic graphs with external legs. This complex comes in particular with a map to the ribbon graph complex computing the (compactly supported) cohomology

We continue studying the cohomology of the hairy graph complexes which compute the rational homotopy of embedding spaces, generalizing the Vassiliev invariants of knot theory, after the second part


This is a note from T. Willwacher’s lecture series which was part of masterclass “Algebraic structure of Hochschild complexes” at the University of Copenhagen in October 2015. From the course

Multi-directed Graph Complexes and Quasi-isomorphisms Between Them II: Sourced Graphs

We prove that the projection from graph complex with at least one source to oriented graph complex is a quasi-isomorphism, showing that homology of the “sourced” graph complex is also equal to the

The Cohomology of the Full Directed Graph Complex

In his seminal paper “Formality conjecture”, M. Kontsevich introduced a graph complex GC 1 v e closely connected with the problem of constructing a formality quasi-isomorphism for Hochschild

On the Caldararu and Willwacher conjectures

. In the present paper, we study a relation between the cohomol- ogy of moduli stacks of smooth and proper curves M g,n and the cohomology of ribbon graph complexes. The main results of this work are

From Deformation Theory of Wheeled Props to Classification of Kontsevich Formality Maps

We study the homotopy theory of the wheeled prop controlling Poisson structures on formal graded finite-dimensional manifolds and prove, in particular, that the Grothendieck–Teichmüller group acts

Classification of universal formality maps for quantizations of Lie bialgebras

We settle several fundamental questions about the theory of universal deformation quantization of Lie bialgebras by giving their complete classification up to homotopy equivalence. Moreover, we

Deformation Theory of Lie Bialgebra Properads

This chapter presents the homotopy derivations of the properads governing even and odd Lie bialgebras, as well as involutive Lie bialgebras. The answer may be expressed in terms of the Kontsevich

Hairy graphs to ribbon graphs via a fixed source graph complex

We show that the hairy graph complex $(HGC_{n,n},d)$ appears as an associated graded complex of the oriented graph complex $(OGC_{n+1},d)$, subject to the filtration on the number of targets, or



On a theorem of Kontsevich

In [12] and [13], M. Kontsevich introduced graph homology as a tool to compute the homology of three infinite dimensional Lie algebras, associated to the three operads "commutative," "associative"

Maurer-Cartan Elements and Cyclic Operads

First we argue that many BV and homotopy BV structures, including both familiar and new examples, arise from a common underlying construction. The input of this construction is a cyclic operad along


We show Koszulness of the prop governing involutive Lie bialgebras and also of the props governing non-unital and unital-counital Frobenius algebras, solving a long-standing problem. This gives us

Deformation theory of representations of prop(erad)s I

Abstract In this paper and its follow-up [Merkulov and Vallette, J. reine angew. Math.], we study the deformation theory of morphisms of properads and props thereby extending Quillen's deformation

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

We show that the zeroth cohomology of M. Kontsevich’s graph complex is isomorphic to the Grothendieck–Teichmüller Lie algebra $$\mathfrak {{grt}}_1$$grt1. The map is explicitly described. This result

Classes on Compactifications of the Moduli Space of Curves Through Solutions to the Quantum Master Equation

In this paper we describe a construction which produces classes in compactifications of the moduli space of curves. This construction extends a construction of Kontsevich which produces classes in

Noncommutative geometry and compactifications of the moduli space of curves

In this paper we show that the homology of a certain natural compactification of the moduli space, introduced by Kontsevich in his study of Witten's conjectures, can be described completely

Homotopy Batalin–Vilkovisky algebras

This paper provides an explicit cobrant resolution of the operad encoding Batalin{Vilkovisky algebras. Thus it denes the notion of homotopy Batalin{Vilkovisky algebras with the required homotopy

Operads and Motives in Deformation Quantization

The algebraic world of associative algebras has many deep connections with the geometric world of two-dimensional surfaces. Recently, D. Tamarkin discovered that the operad of chains of the little
