Tensorization of quasi-Hilbertian Sobolev spaces
Sylvester Eriksson-Bique, Tapio Rajala, Elefterios Soultanis
The tensorization problem for Sobolev spaces asks for a characterization of how the Sobolev space on a product metric measure space can be determined from its factors.…
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…
Tensorization of -weak differentiable structures
Sylvester Eriksson-Bique, Tapio Rajala, Elefterios Soultanis
We consider -weak differentiable structures that were recently introduced by the first and last named authors, and prove that the product of -weak charts is a -weak chart.…
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…
