Two-point one-dimensional $\delta$-${\delta }^{\prime }$ interactions: non-abelian addition law and decoupling limit

M. Gadella, J. Mateos Guilarte, J. M. Munoz-Castaneda +1

In this contribution to the study of one dimensional point potentials, we prove that if we take the limit $q\to 0$ on a potential of the type $v_0δ({y})+{2}v_1δ'({y})+w_0δ({y}-q)+…
