Abstrakt:

We deal with the Hamiltonians with a spherically symmetric repulsive potential. For such Hamiltonians we prove Rellich's theorem, or identify the largest weighted space of Agmon-Hörmander type where the generalized eigenfunctions are absent. By considering Rellich's theorem we obtain the locally uniform boundedness of the resolvent between appropriate function spaces. This is a stronger estimate than the usual one.
