In addition to basic arithmetic in
, BERNINA provides the following
operations on differential operators:
`adjoint`, `apply`, `coefficient`,
`Darboux`, `decompose`, `degree`, `diff`,
`eigenring`, `element`, `exponentialSolutions`,
`exteriorPower`,
`factor`,
`kernel`,
`leftGcd`, `leftLcm`, `Loewy`,
`makeIntegral`, `normalize`,
`polynomialSolution`,
`radicalSolutions`, `rationalSolution`,

`rightGcd`, `rightLcm`,
`symmetricKernel`, `symmetricPower` and `system`.
They are described in detail in the following manual pages.
Note that an element of
can be used
whenever the type of an argument is given as
,
and that computes the Euclidean quotient of
by on the right.
