Filling minimality and Lipschitz-volume rigidity of convex bodies among integral current spaces
Giuliano Basso, Paul Creutz, Elefterios Soultanis
In this paper we consider metric fillings of convex bodies. We show that convex bodies are the unique minimal fillings of their boundary metrics among all i…
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.…
Causal bubbles in globally hyperbolic spacetimes
Leonardo García-Heveling, Elefterios Soultanis
We give an example of a spacetime with a continuous metric which is globally hyperbolic and exhibits causal bubbling. The metric moreover splits orthogonally into a timelike and a…
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.…
