- Abstract
In this note, we deal with the fractional logarithmic Schrödinger operator (I + (- Δ) s) log and the corresponding energy spaces for variational study. The fractional (relativistic) logarithmic Schrödinger operator is the pseudo-differential operator with logarithmic Fourier symbol, log (1 + | ξ | 2 s) , s > 0 . We first establish the integral representation corresponding to the operator and provide an asymptotics property of the related kernel. We introduce the functional analytic theory allowing to study the operator from a PDE point of view and the associated Dirichlet problems in an open set of R N. We also establish some variational inequalities, provide the fundamental solution and the asymptotics of the corresponding Green function at zero and at infinity. [ABSTRACT FROM AUTHOR]
