Spectral properties of non-selfadjoint extensions of the Calogero Hamiltonian
G. Metafune, M. Sobajima
We describe all extensions of the Calogero Hamiltonian \[L=-\frac{d^2}{dr^2}+\frac{b}{r^2} \quad \text{in}\ L^2(\mathbb{R}_+), \quad b <-\frac{1}{4}\] having non empty resolvent an…

Scale invariant elliptic operators with singular coefficients
G. Metafune, N. Okazawa, M. Sobajima +1
We show that a realization of the operator generates a semigroup in if and only if $D_c=b+(N-2+c)^2/4…
