Math. 447 (1994) 91-145), is studied. As Cantor's approach is algebraic, another derivation is presented as a natural extension of the analytic derivation of the recursion relation of the elliptic psi function.AMS-TeX, 18 pagesMathematical PhysicsAlgebraic GeometryNumber TheoryExactly Solvable and Integrable Systemstext
