### The multi-marginal optimal transportation problem and minimal networks

PDE and Applied Math Seminar

 Speaker: Jonathan Dahl, UC Berkeley Location: 1147 MSB Start time: Tue, May 1 2012, 3:10PM

I will discuss the multi-marginal generalization of the optimal transportation problem, as well as the related minimal network problem in $L^2$ Wasserstein space. For the minimal network problem, I will also show methods for obtaining pointwise entropy and $L^\infty$ estimates.
