||Sobolev Extensions of HÃ¶lder Continuous and Characteristic Functions on Metric Spaces |
We study when characteristic and H\"older continuous functions
are traces of Sobolev functions on doubling metric measure spaces.
We provide analytic and geometric conditions sufficient for extending
characteristic and H\"older continuous functions into globally defined
