| dc.description.abstract | We determine explicitly a boundary triple for the Dirac operator H := -ia .V + mB + V(x) in R3 , for m c R and V(x) = IxI-1(vI4 + µB-il. x/IxIB), with v, µ, l c R. Consequently, we determine all the self-adjoint realizations of H in terms of the behavior of the functions of their domain in the origin. When supxIxIIV(x)<=1, we discuss the problem of selecting the distinguished extension requiring that its domain is included in the domain of the appropriate quadratic form. | es_ES |
