On the traces of Sobolev functions on the boundary of a cusp
with a Hölder singularity
For the Sobolev classes Wp1 on a “zero”
cusp with a Holder singularity at the vertex, we consider the question
of compactness of the embedding of the traces of Sobolev functions into
the Lebesgue classes on the boundary of the cusp.
