We construct, for any given l=12+N0, the second-order, linear partial differential equations (PDEs) which are invariant under the centrally extended conformal Galilei algebra. At the given l, two invariant equations in one time and l+12 space coordinates are obtained. The first equation possesses a continuum spectrum and generalizes the free Schrodinger equation (recovered for l=12) in 1 + 1 dimension. The second equation (the “l-oscillator”) possesses a discrete, positive spectrum. It…
