Closed form solutions of linear odes having elliptic functions as coefficients

R. Burger, G. Labahn, M. van Hoeij

 

We consider the problem of finding closed form solutions of linear differential equations having coefficients which are elliptic functions. For second order equations we show how to solve such an ode in terms of doubly periodic functions of the second kind. The method depends on two procedures, the first using a second symmetric power of an ode along with a decision procedure for determining when such equations have elliptic function solutions while the second uses computation of exponential solutions.
