DEtools[RationalCanonicalForm] - construct two differential rational canonical forms of a rational function
Calling Sequence
RationalCanonicalForm[1](F, x)
RationalCanonicalForm[2](F, x)
Parameters
F
-
rational function of x
x
variable
Description
Let F be a rational function of x over a field K of characteristic 0. The RationalCanonicalForm[i](F,x) calling sequence constructs the ith differential rational canonical forms for F, .
If the RationalCanonicalForm command is called without an index, the first differential rational canonical form is constructed.
The output is a sequence of 2 elements , called RationalCanonicalForm(F), where are rational functions over K such that
.
If the third optional argument, which is the name 'polyform', is given, the output is a sequence of 4 elements , where are polynomials over K, monic such that , .
The use of RationalCanonicalForm[1] is for testing similarity of two given hyperexponential functions. For RationalCanonicalForm[2], the polynomials are also pairwise relatively prime. RationalCanonicalForm[2] is used in a reduction algorithm for hyperexponential functions.
