,An Application of the Lamé Equation,n and A and . are, in general, complex parameters. It is assumed, in what follows, that the roots of the polynomial . associated to . are simple (otherwise . is reduced to elementary functions). This is ensured if the discriminant.is non-zero, where g. and g. are the associated invariants (see Chapter 2).
