We use the classical techniques to establish this variational lemma. We also point out several questions concerning the zeros of the solutions to fractional Laplace equations which play an important role in the qualitative theory of fractional Laplace equations.falseFractional Laplacian | Leighton's variational lemma | Variational methodsArticle461-47320181arJournal1WOS:000447632800005
