“…Later on, an approach which does not suffer from this ambiguity was devised by Jensen and Koppe [4] in the 1970s and by Da Costa [5,6] in the 1980s, showing that a geometry-induced potential (GIP) acts upon the dynamics 1 . Since then, some research on the subject has been reported, such as a path integral formulation [13,14], effects on the eigenstates of nanostructures [15,16], interaction with an electromagnetic potential [17,18,19,20], modeling of bound states on conical surfaces [21,22,23], spinorbit interaction [24,25,26], electronic transport in nanotubes [27,28], and bent waveguides [11,29,30,31], just to name a few.…”
