Abstract:
We present some new results dealing with regularity, existence, and multiplicity of weak solutions for elliptic boundary value problems driven by the fractional $p$-Laplacian, and involving several types of reactions both bounded and unbounded. Special emphasis will be placed on boundary H\older regularity, and the ways it affects comparison principles, existence of minimizers, a priori bounds, and multiplicity of solutions as an outcome.
