IRP on Higher Homotopical Structures​

WORKSHOP: Higher Structures and Operadic Calculus (IRP Higher Homotopical Structures)

Sign in
From April 12, 2021
to April 16, 2021
Registration deadline 04 / 04 / 2021


Since their introduction 50 years ago, the notions of infinity-algebras (Stasheff), operads (May), model categories (Quillen), and higher categories (Boardman-Vogt) gave rise to powerful tools which made possible the resolution of open problems and prompted revolutions in many domains like algebraic topology (rational homotopy theory, faithful algebraic invariants of the homotopy type of spaces), deformation theory (formality theorems, formal moduli problems), and mathematical physics (quantisation of Poisson manifolds, quantum field theories), to name but a few. This theory of higher structures using operadic calculus is currently under rapid development and there is a need today to provide the community with a modern state of the art; this is the main goal of the present workshop, which will be accessible to a wide audience.​

Workshop’s ​information

  • Rational homotopy theory, Lie/L-infinity-models, Koszul duality, Maurer-Cartan spaces.
  • Configuration spaces, holonomy algebras, connections, associators, operads in groupoids, (prounipotent) Grothendieck-Teichmüller group.
  • Deformation theory, Maurer-Cartan elements, integration theory (gauge group, pre-Lie calculus, infinity-groupoids), formal moduli spaces.
  • Infinity-operads, formality theorems, Hodge theory (purity).
  • (Infinity-)modular operads, moduli spaces of curves, (profinite) Grothendieck-Teichmüller group.
