The conference will be preceded by a mini-course on commutative rings, integer-valued polynomials and polynomial functions Dec. 16-18, 2012, taught by the main speakers of the conference.

From the website:

The theme of this two week event will be a survey of the state of the art in the use of cohomology and supports in the study of representation theory. The first week will be a prepatory summer school intended for graduate students, recent doctoral recipients, or others new to the field to introduce the fundamental ideas. Three speakers will each present a series of four lectures. The second week of the conference will consist of talks on latest develoments in the field with ample time for discussion and collaboration.

The summer school speakers will be Paul Balmer, Dave Benson, and Srikanth Iyengar. See the web page for more information about the school and the conference.

“Additive Combinatorics in Paris 2012″ will be held at the Institut Henri Poincaré in Paris during the week 9th-13th July 2012. The conference will be dedicated to the memory of Yahya ould Hamidoune, who passed away earlier this year. As such, the scope of the conference encompasses topics in additive and combinatorial number theory, additive group theory, graph theory and probabilistic combinatorics as well as adjacent fields.

In particular, this also includes certain topics on the arithmetic of commutative domains and monoids (Dedekind, Krull, numerical,…), in which Yahya had an active interest, where methods from additive combinatorics are key. There will be at least two talks, by A.Geroldinger (plenary) and S.T.Chapman. which will discuss such arithmetic aspects.

There will be a special talk on Yahya’s mathematical achievements, a movie documenting his battle against environmental destruction in his native Mauritania as well as a themed conference dinner.

Deadlines

Registration is required by April 15. Applications for funding and for contributed talks will be considered until March 15th. Check out the registration page on our the school’s web page.

Aims of the school

The school’s lectures will be mainly aimed at Ph. D. students and young researchers, and should be of interest for all researchers in this area of mathematics, as it should cover many of the combinatorial, topological, algebraic and geometric aspects of the topic. Participants are encouraged to propose contributed talks of 30 minutes.

Sponsors

The school is financed by the ANR projects ANR Interlow, ANR GeoLMI, by the department of mathematics LMA in Pau, by the Institut Pluridisciplinaire de Recherche Appliquee, by GDR Geometrie Algebrique et Geometrie Complexe, GDR Tresses, GDR Singularites, Conseil de la Recherche de l’Universite de Pau, Conseil Regional d’Aquitaine, Communaute d’agglomeraiton de Pau, Conseil General 64.

The school will take place at Pau’s university Campus. Lectures should begin on Monday 11 in the morning, and end on Friday the 15th before lunch.
