diffalg.PseudoReduce

calculate a pseudo normal form of a differential polynomial

Syntax

$diffalg.PseudoReduce(F:POLY, G:LIST):POLY

Description

PseudoReduce computes the pseudo normal form of the differential polynomial F wrt. the list G of differential polynomials.

Example

Use Q[x[1..1,0..20]];
Use Q[x[1..1,0..20]], Ord($diffalg.DiffTO("Lex"));
$diffalg.PseudoReduce(x[1,1]^4+x[1,0], [x[1,0]^2+3x[1,0]]);
-------------------------------
-3x[1,0]
