Nonlinear singular perturbations of the fractional Schrödinger equation in dimension one

Raffaele Carlone, Domenico Finco, Lorenzo Tentarelli

The paper discusses nonlinear singular perturbations of delta type of the fractional Schrödinger equation $ı{\partial }_t\psi ={\left(-△\right)}^s\psi$, with $s\in (\frac{1}{2},1]$…
