Abstract: Let D and H be the self-adjoint, one-dimensional Dirac and Schrdinger operators in L 2 (; 2 ) and L 2 (; ) respectively. It is well known that, in absence of an external potential, the two operators are related through the equality D 2 = (H + 1 4 ) . We show that such a kind of relation also holds in the case of n -point singular perturbations: given any self-adjoint realization
