DA.PseudoReduce

Calculate a pseudo normal form of a differential polynomial.

Syntax

DA.PseudoReduce(F:POLY, G:LIST):POLY

Description

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

• @param F Differential polynomial for which to compute the pseudo normal.

• @param G List of differential polynomials wrt. which the normal form of F has to be computed.

• @return The pseudo normal form of F wrt. G.

Example

Use QQ[x[1..1,0..20]];
Use QQ[x[1..1,0..20]], Ord(DA.DiffTO(<quotes>Lex</quotes>));
DA.PseudoReduce(x[1,1]^4+x[1,0], [x[1,0]^2+3x[1,0]]);
