WebNov 1, 2024 · We study the boundary traces of Newton-Sobolev, Hajlasz-Sobolev, and BV (bounded variation) functions. Assuming less regularity of the domain than is usually done in the literature, we show that all of these function classes achieve the same "boundary values", which in particular implies that the trace spaces coincide provided that they exist. … WebA general theory of SBV functions was developed by Ambrosio [1-3] to find solutions to a large class of problems, via suitable com-pactness and lower semicontinuity results.

WebAbstract. Three density theorems for three suitable subspaces of S B D functions, in the strong B D topology, are proven. The spaces are S B D, S B D ∞ p, where the absolutely continuous part of the symmetric gradient is in L p, with p > 1, and S B D p, whose functions are in S B D ∞ p and the jump set has finite H n − 1 -measure.
