%0 Journal Article %T Mathematical justification of the Aharonov-Bohm hamiltonian %A Cesar R. de Oliveira %A Marciano Pereira %J Mathematics %D 2008 %I arXiv %R 10.1007/s10955-008-9631-y %X It is presented, in the framework of nonrelativistic quantum mechanics, a justification of the usual Aharonov-Bohm hamiltonian (with solenoid of radius greater than zero). This is obtained by way of increasing sequences of finitely long solenoids together with a natural impermeability procedure; further, both limits commute. Such rigorous limits are in the strong resolvent sense and in both $\R^2$ and $\R^3$ spaces. %U http://arxiv.org/abs/0810.0684v1
