Is the sum of optimal transports again optimal?

Seminario de jóvenes investigadores. "Is the sum of optimal transports again optimal?" by Ruben Medina Sabino. Abstract: We are going to talk about the connections between the transportation cost space (also known as Lipschitz free space) and the canonical Banach space $\ell_1$. We will give a partial answer to a problem posed by Dilworth, Kutzarova and Ostrovskii in 2020 and that has been around since these spaces were defined. Namely, to find a metric characterization of the Banach-Mazur distance between the Lipschitz free space and $\ell_1$ La ponencia también podrá seguirse a través del enlace https://meet.google.com/uoh-dyyr-jss
