Oscillatory Phenomena for Higher-Order Fractional Laplacians

Nicola Abatangelo, Sven Jarohs

We collect some peculiarities of higher-order fractional Laplacians $(- Δ)^{s}$ , $s > 1$ , with special attention to the range $s \in (1, 2)$ , which show their oscillatory nature. These inc…

On the shape of the first fractional eigenfunction

Nicola Abatangelo, Sven Jarohs

We show that the first eigenfunction of the fractional Laplacian $(- Δ)^{s}$ , $s \in (1/2, 1)$ , is superharmonic in the unitary ball up to dimension $11$ . To this aim, we also rely on…
