Serrin-type theorems for domains with disconnected boundary

Abstract We prove symmetry results for solutions to the torsion problem on domains with disconnected boundary. Time permitting, we discuss their relations with the uniqueness theorem for the Schwarzschild-de Sitter static black hole in general relativity.

People external to SNS, or people willing to attend the event remotely, should write to andrea.malchiodi@sns.it  and ask to join the "MS Teams" group of the seminars.
