Résumé:	EDP & Physique mathématique - Singularities in the Keller-Segel system -
Description:	Van Tien Nguyen The talk will present constructive examples of finite-time blowup solutions to the Keller-Segel system in $L^1$-critical ($d = 2$) and $L^1$-supercritical regimes ($d geq 3$). It's interesting that the radially symmetric profile of collapsing-ring solution in the higher dimensional case is linked to the traveling-wave of the 1D viscous Burgers equation.
