    • 2015, Kamil Kaleta, Mateusz Kwaśnicki, József Lőrinczi, “Contractivity and ground state domination properties for non-local Schrödinger operators”, in arXiv[1]:
      As a consequence, we obtain for a large subclass of confining potentials that, on the one hand, supercontractivity and ultracontractivity, on the other hand, hypercontractivity and asymptotic ultracontractivity of the transformed semigroup are equivalent properties.
