Scientific program

  This is a working group: each participant presents a paper(s) (not from him) that she (he) finds interesting. There are time for dicussions among the participants.

Some propositions of talks:

     We will take time for each presentation if needed. (may be half a day).

•  Anke Pohl :  article of M.Ratner about  correlations of geodesic and horocycle flow.
•  Tobias Weich et Charles Hadfield:  article de S. Dyatlov et M. Zworski sur la fonction zeta dynamique des flots Anosov.
• Colin Guillarmou:  about inverse problem
•  Yves Colin de Verdiere: article de R. Melrose sur le thème "Laplacien sous Riemanien" and related topics.
• (Frederic Faure ?): articles récents de Liverani "Fast-slow partially hyperbolic systems: beyond averaging.
• Stephane Nonenmacher, (& Gabriel  Riviere ?):  papier de Gayet-Welschinger sur le comptage de domaines nodaux (arXiv:1406.0934v1) ou  un papier de Burq & Zuily sur la concentration des modes propres du laplacien dans des voisinages fins de sous-variétés (arXiv:1503.02058v1).

• Dmitry Jakobson : I would like to give a survey of the following papers (learned about them at Banff last week): http://math.umn.edu/~svitlana/publications.html in the middle of the page, under "localization". The authors are S. Mayboroda, M. Filoche, G. David, D. Jerison et al. They study localization of eigenfunctions whose eigenvalues is not too large, and it seems there is strong correlation with a certain "landscape function". This is interesting in applications, I think, since there you cannot access very high energy efxns.

• Ingo Witt: "Anderson localization on graphs" (with a nearest-neighbor Laplacian) There has recently been some activity in this field, see e.g. Chulaevsky's talk at the Newton Institute https://www.newton.ac.uk/event/pep/seminars.

• Maxime Ingremeau et Yannick Bonthonneau: article de Gell-Redman et Hassell intitulé "Potential scattering and the continuity of phase-shifts" et "Equidistribution of phase shifts in semiclassical potential scattering " par Jesse Gell-Redman, Andrew Hassell, Steve Zelditch.

Transport

Arrival:  in Peyresq will be sunday  24 mai 2015 in the afternoon or the evening.

For people coming from Nice:

• Informations for Nice airport -> "Train des pignes" station in Nice.
• "Train des pignes" station in Nice: here is on google map. (This is close to but different from the national SNCF train station).

• Here are the time table for the  "train des pignes": Nice -> Meailles:

http://tourisme.trainprovence.com/horaires-urbains-interurbains/

I propose to take the train in Nice a 17h15   -> Meailles  19h20
or the one before: Nice  13h05 -> Meailles 15h01.

• Then a car will take you in Meailles to Peyresq.

For people coming from grenoble:

        There will be two cars: Yves & Marie Jo,  Frédéric

with   7 + 3 = 10 places. 

• Une autre possibilité pour les randonneurs avertis, n'ayant pas de valise, mais un sac à dos, est de s'arreter à l'arrêt de Peyresq et de monter à pied à Peyresq en suivant le chemin indiqué sur la carte. Il y a 500m de dénivelé.

Departure: saturday 30 mai (or friday 29 mai).

• I propose that  people take the "train des pignes" 30/5/2015:  Train Meailles (8h35) –> Nice CP (10h30).
