*The brutal death in Cairo in January 2016 of Giulio Regeni, an Italian doctoral student at Cambridge University, prompted an international letter calling for an independent enquiry that quickly gained 4600 signatures. This was formally delivered to the Egyptian Embassy in London on 22 March. The Deputy Chief of Mission, Mr Hassan Shawky, received the letter and discussed the request with a group of eight teachers and researchers from Cambridge and London universities who reflected a cross-section of the signatories.*

for details.

# Lectureship positions in Cambridge

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):
