The adverts for the 3 Lectureships in Pure Mathematics are now live with closing deadline as December 15th. One of the positions is the Corfield Lectureship (linked post with Murray Edwards). Another fourth position is open in Probability.

# The Princeton Companion to Applied Mathematics

The Princeton Companion to Applied Mathematics just appeared:

It includes an introductory article on kinetic theory I wrote together with Cédric Villani, and many other interesting papers.

# New preprint: Hölder continuity of solutions to quasilinear hypoelliptic equations (w/ C. Imbert)

http://arxiv.org/abs/1505.04608

We prove that weak solutions to a quasilinear hypoelliptic equations with bounded measurable coefficients are H\”older continuous. The proof relies on classical techniques developed by De Giorgi and Moser together with the averaging lemma and regularity transfers developed in kinetic theory. The latter tool is used repeatedly: first in the proof of the local gain of integrability of sub-solutions, second in proving that the gradient with respect to the speed variable is , third, in the proof of an “hypoelliptic isoperimetric De Giorgi lemma”. To get such a lemma, we develop a new method which combines the classical isoperimetric inequality on the diffusive variable with the structure of the integral curves of the first-order part of the operator. It also uses that the gradient of solutions w.r.t. v is .

# Birth of a Theorem… Villani on the BBC

Cédric Villani was on BBC 2 on the occasion of the publication of the book “Birth of a Theorem” (translation of his book “Théorème vivant” describing the making of our theorem).

Here is the link (Villani starts at 37:45):

# Describing Patterns – a movie by Sameer Patel & Sara Merino-Aceituno

A 10mn movie about the scientific research of Sara Merino-Aceituno, PhD student co-supervised by myself and James Norris, and featuring several other members of the “geometric analysis and partial differential equations” group in Cambridge:

# Statement by some academics at the University of Cambridge about Gaza

# Oxbridge PDE conference 2014

This annual conference is held alternately in Oxford and Cambridge UK, and is focused on analysis and PDE.

It will held this year in Cambridge on the 20-21 March, 2014 in the CMS.
