A necessary condition for Sobolev extension domains in higher dimensions

Miguel García-Bravo, Tapio Rajala, Jyrki Takanen

We give a necessary condition for a domain to have a bounded extension operator from to for the range . The condition is given in ter…

Zero volume boundary for extension domains from Sobolev to

Tapio Rajala, Zheng Zhu

In this note, we prove that the boundary of a -extension domain is of volume zero under the assumption that the domain $\boz$ is -fat at almost every $x\in\parti…

Multi-marginal Entropy-Transport with repulsive cost

Augusto Gerolin, Anna Kausamo, Tapio Rajala

In this paper we study theoretical properties of the entropy-transport functional with repulsive cost functions. We provide sufficient conditions for the existence of a minimizer i…

Duality theory for multi-marginal optimal transport with repulsive costs in metric spaces

Augusto Gerolin, Anna Kausamo, Tapio Rajala

In this paper we extend the duality theory of the multi-marginal optimal transport problem for cost functions depending on a decreasing function of the distance (not necessarily bo…

Non-existence of optimal transport maps for the multi-marginal repulsive harmonic cost

Augusto Gerolin, Anna Kausamo, Tapio Rajala

We give an example of an absolutely continuous measure on , for any , such that no minimizer of the -marginal harmonic repulsive cost with all marginal…

estimates in optimal mass transportation

Heikki Jylhä, Tapio Rajala

We show that in any complete metric space the probability measures with compact and connected support are the ones having the property that the optimal tranportation distance t…
