  • In this work we prove a strong maximum principle for fractional elliptic problems with mixed Dirichlet;Neumann boundary data which extends the one proved by J. D├ívila (cf. [11]) to the fractional setting. In particular, we present a comparison result for two solutions of the fractional Laplace equation involving the spectral fractional Laplacian endowed with homogeneous mixed boundary condition. This result represents a non–local counterpart to a Hop
