DESCRIPTION:Speakers: Ulrik Skre Fjordholm (University of Oslo)\nInspired
by so-called TVD limiter-based second-order schemes for hyperbolic conserv
ation laws\, we develop a second-order accurate numerical method for multi
-dimensional aggregation equations. The method allows for simulations to b
e continued after the first blow-up time of the solution. In the case of s
ymmetric\, lambda-convex potentials with a possible Lipschitz singularity
at the origin we prove that the method converges in the Monge--Kantorovich
distance towards the unique gradient flow solution. This is joint work wi
th JosÃ© A. Carrillo and Susanne Solem.\n\nhttps://indico.math.cnrs.fr/eve
