Henri Lebesgue Center offers post-doc positions for researchers in mathematics.

Description

The Lebesgue Center and its partners, Région Bretagne & Région Pays de la Loire (DéfiMaths project), are opening applications for three post-doctoral positions in mathematics for a period of 2*12 months. The hired applicant will conduct his/her research at one of these Insitutes:

Irmar of Rennes
LMJL of Nantes
LMBA of Brest and Vannes
LAREMA of Angers

The positions are open to all research areas present within the four Institutes. They do not include an obligation to teach.

The net salary will be 2 100 Euros per month.

Deadlines

The application is open.

Sending application: between the 4th of October 2017 and the 1st of December 2017.

The positions are expected to begin on September 1st or October 1st, 2018.

School - Masterclass 2017

Angers, from December 19th to December 21st

Organization board: Etienne Mann

We organize a masterclass in Angers, from 19th to 21st of December, 2017. Lectures will be in the morning sessions. We will have two parallel sessions:

Etienne Mann : Introduction to algebraic stacks
We will introduce the notion of fibered category, Grothendieck topology and stacks. We will illustrate these notions on simple examples. These lectures are for Master (or PhD) students who had followed a introduction to algebraic geometry that is algebraic varieties and sheaves.
Loic Chaumont: Application of the matrix-tree-theorem

The organisation board will pay the housing and the lunch. The other meals are not payed by the organizers. For the travel expenses, we will do our best in the limit of our budget.

Date limite d'inscription 15 novembre.

Analysis on homogeneous cones and beyond

The set of positive definite real symmetric matrices is a typical example of homogeneous cone. Because of its rich symmetry, a lot of beautiful integral formulas hold over the homogeneous cone. And recently, statisticians find that some of the formulas are valid even for non-homogeneous cones.
