Le séminaire Bourbaki délocalisé au Luxembourg

[celigne]

This took the mathematicians back to near the Amphitheatre where the lecture was originally scheduled, and they decided to continue the lecture there rather than outdoors in the Panthéon, for fear of being interrupted by gendarmes on some other ground.

Normally the lecture would have been given indoors, but in a show of solidarity with the academic strikes sweeping France the lecture was moved to the Jardin Luxembourg a couple of blocks to the west of the Institute. The gendarme breaking up the lecture at the end is pointing out that public lectures are forbidden in the park because it is owned by the senate, and suggests the Place du Panthéon as an alternative.

The lecturer is Gerard Besson of the Université

de Grenoble, the last of five mathematicians who spoke at the Séminaire Nicolas Bourbaki held at the Institut Henri Poincaré the weekend of 14-15 March 2009. His topic is Brendle and Schoen's differential sphere theorem, that for a compact finite-dimensional Riemannian manifold with sectional curvature in the interval (.25,1), the manifold is diffeomorphic to a spherical space form.
