Uniqueness of Radial Solutions for the Fractional Laplacian

Rupert L. Frank, Enno Lenzmann, Luís Silvestre

Short summary

This paper proves that radial, bounded solutions vanishing at infinity for fractional Laplacian equations (−Δ) s + V (with s ∊ (0,1) and V radial/nondecreasing) are unique, implying simple radial eigenvalues. It also establishes unique and non-degenerate ground states for nonlinear versions of these equations.
