A geometric characterization for planar Sobolev extension domains


We explain our recent joint results with Tapio Rajala and Yi Zhang that give a geometric characterization for those bounded simply-connected planar domains that admit an extension operator for the usual first-order Sobolev space of integrability degree p less than 2.


The Catalan Mathematical Society invites participants to this first congress of a biannual series focusing on current research topics across several areas of Mathematics.

Plenary talks and thematic sessions have been selected by the Scientific Committee of the SCM. Special thanks are due to the organisers of the thematic sessions and to the local mathematical community as a whole for their support to this congress.
