We study the representation theory of the solution space of the one-dimensional Schrödinger equation with singular potential Vλ(x) = λx−2 as a representation of \(\widetilde{SL(2,\mathbb{R})}\). The subspace of solutions for which the action globalizes is constructed via nonstandard induction outside the semisimple category. By studying the subspace of K-finite vectors in this space, a distinguished family of potentials, parametrized by the triangular numbers is shown to generate a global representation of \(\widetilde{SL(2,\mathbb{R})}\)H3, where H3 is the three-dimensional Heisenberg group.
