Abstract:
 The n-dimensional Schrodinger equation with a singular potential
 $V_\lambda(x)=\lambda \|x\|^{-2}$ is studied.
 Its solution space is studied as a global representation of
 $\widetilde{SL(2,\mathbb{R})}\times O(n)$. A special subspace of solutions
 for which the action globalizes is constructed via nonstandard
 induction outside the semisimple category. The space of K-finite
 vectors is calculated, obtaining conditions for $\lambda$ so that this
 space is non-empty. The direct sum of solution spaces over such admissible
 values of $\lambda$ is studied as a representation of the (2n+1)-dimensional
 Heisenberg group.
