Regard croisé sur deux pratiques d’analyses du mouvement

L’analyse du
mouvement selon Laban (LMA) et l’analyse fonctionnelle du corps dans le
mouvement dansé (AFCMD)
L’analyse du mouvement selon Laban (LMA) et l’analyse fonctionnelle du corps dans le mouvement
dansé (AFCMD) sont deux approches d’analyse du mouvement qui s’intéressent au même objet,
l’expressivité du corps en mouvement, mais qui ont été créées à des époques et à partir de
préoccupations très différentes. Cependant, ces deux approches sont inévitablement appelées à se
rejoindre dans la réalité de l’expérience du mouvement.
L’objectif principal de cette recherche est de tenter d’identifier des correspondances, des
complémentarités, des convergences et des divergences entre les deux approches en partant de
l’activité perceptive des personnes expertes de ces deux approches, dans une tâche d’observation des
mêmes mouvements, à partir d’un enregistrement vidéo.
Nicole Harbonnier-Topin est titulaire d’un doctorat en Formation des adultes du Conservatoire
National des Arts et Métiers et professeure au Département de danse de l’Université du Québec à
Montréal dans le champ de l’analyse du mouvement et de l’éducation somatique. Elle est certifiée en
Analyse Fonctionnelle du Corps dans le Mouvement Dansé.

« Mise en présence » des enjeux d’incorporation
dans une expérience de recherche chorégraphique
Le format hybride de cette intervention, au croisement de la «recherche-création» et de la
« conférence dansée », représente une étape de ma recherche chorégraphique et doctorale.
Il me permet de présenter un moment de pratique théorique qui peut nous aider à questionner la
création contemporaine en danse et à développer des hypothèses d’analyse à partir de la perception
sensible du mouvement et des modalités du langage utilisé en situation. La création en danse
contemporaine est une rencontre, elle est le lieu et le temps d’un partage. Il s’agit d’un rapport
interactif où la transmission de la danse singulière du chorégraphe investit le danseur à part entière
avec toutes ses ressources, humaines et professionnelles. Dans mon intervention une danseuse (une de
mes collaborateurs, ma sœur) expose son corps aux variables suggérées par la chorégraphe/chercheuse
(moi-même). Ce corps et ses réactions sont analysés en fonctions des prémisses chorétiques et des
résultats obtenus.
Alessandra Sini est doctorante à l’Université de Nice Sophia Antipolis, danseuse, enseignante et
chorégraphe pour la compagnie « Sistemi dinamici altamente instabili ». Elle étudie le corps et ses
transformations dans la recherche chorégraphique italienne récente en articulant pratiques
artistiques et champ théorique.

Andras Vasy - Microlocal analysis and wave propagation (Part 2)
/ Fanny Bastien
/ Canal-u.fr
Voir le résumé
Voir le résumé
In these lectures I will explain the basics of microlocal analysis, emphasizing non elliptic problems, such as wave propagation, both on manifolds without boundary, and on manifolds with boundary. In the latter case there is no `standard' algebra of differential, or pseudodifferential, operators; I will discuss two important frameworks: Melrose's totally characteristic, or b, operators and scattering operators. Apart from the algebraic and mapping properties, I will discuss microlocal ellipticity, real principal type propagation, radial points and generalizations, as well as normally hyperbolic trapping. The applications discussed will include Fredholm frameworks (which are thus global even for non elliptic problems!) for the Laplacian on asymptotically hyperbolic spaces and the wave operator on asymptotically de Sitter spaces, scattering theory for `scattering metrics' (such as the `large ends' of cones), wave propagation on asymptotically Minkowski spaces and generalizations (`Lorentzian scattering metrics') and on Kerr de Sitter type spaces. The lectures concentrate on linear PDE, but time permitting I will briefly discuss nonlinear versions. The lecture by the speaker in the final workshop will use these results to solve quasilinear wave equations globally, including describing the asymptotic behavior of solutions, on Kerr de Sitter spaces.

Christian Gérard - Construction of Hadamard states for Klein‐Gordon fields
/ Fanny Bastien
/ Canal-u.fr
Voir le résumé
Voir le résumé
we will review a new construction of Hadamard states for quantized Klein-‐Gordon fields on curved spacetimes, relying on pseudo differential calculus on a Cauchy surface. We also present some work in progress where Hadamard states are constructed from traces of Klein-‐Gordon fields on a characteristic cone. (Joint work with Michal Wrochna).

Christian Gérard - Introduction to field theory on curved spacetimes (Part 2)
/ Fanny Bastien
/ Canal-u.fr
Voir le résumé
Voir le résumé
The aim of these lectures is to give an introduction to quantum field theory on curved spacetimes, from the point of view of partial differential equations and microlocal analysis. I will concentrate on free fields and quasi-free states, and say very little on interacting fields or perturbative renormalization. I will start by describing the necessary algebraic background, namely CCR and CAR algebras, and the notion of quasi-free states, with their basic properties and characterizations. I will then introduce the notion of globally hyperbolic spacetimes, and its importance for classical field theory (advanced and retarded fundamental solutions, unique solvability of the Cauchy problem). Using these results I will explain the algebraic quantization of the two main examples of quantum fields ona manifold, namely the Klein-Gordon (bosonic) and Dirac (fermionic) fields.In the second part of the lectures I will discuss the important notion of Hadamardstates , which are substitutes in curved spacetimes for the vacuum state in Minkowskispacetime. I will explain its original motivation, related to the definition of therenormalized stress-energy tensor in a quantum field theory. I will then describethe modern characterization of Hadamard states, by the wavefront set of their twopointfunctions, and prove the famous Radzikowski theorem , using the Duistermaat-Hörmander notion of distinguished parametrices . If time allows, I will also describe the quantization of gauge fields, using as example the Maxwell field.
