rationalSolution

Usage

rationalSolution(L, g)

Parameter	Type	Description
L	$\mathbbm{Q}[x,\frac d{dx}]$	A differential operator
g	$\mathbbm{Q}(x)$	A fraction

Description

rationalSolution($L,g$) returns either $[f]$ where $f \in \mathbbm{Q}(x)$ satisfies $L f = g$, or $[]$ if $L y = g$ has no solution in $\mathbbm{Q}(x)$.

Remarks

rationalSolution($L,0$) returns $[0]$ only when $L y = 0$ has no nonzero rational solution.

Usage within MAPLE

• When using rationalSolution from inside MAPLE, the output is modified and either a rational solution in $f \in \mathbbm{Q}(x)$ or $[]$ is returned.
