The dirichlet problem for nonlocal operators
WebDec 7, 2024 · Abstract We obtain a critical imbedding and then, concentration-compactness principles for fractional Sobolev spaces with variable exponents. As an application of these results, we obtain the existence of many solutions for a class of critical nonlocal problems with variable exponents, which is even new for constant exponent case. Webthat maps fto a nonlocal analogue of the Neumann boundary value of the solution u. (This discussion assumed that is a bounded Lipschitz domain, see Section 2 for the case of general bounded open sets.) We will de ne qvia the bilinear form associated with the fractional Dirichlet problem. There are other nonlocal Neumann operators that
