DA.PseudoAutoReduce
Calculate a pseudo reduced list of differential polynomials.
Syntax
DA.PseudoAutoReduce(G:LIST):LIST
Description
DA.PseudoAutoReduce returns a pseudo reduced list, i.e., every element of G reduces
to zero with respect to the returned list.
@param G List of differential polynomials.
@return An autoreduced list of differential polynomials.
Example
Use Q[x[1..2,0..20]];
Use Q[x[1..2,0..20]], Ord(DA.DiffTO("Lex"));
DA.PseudoAutoReduce([x[1,1]^4 + x[2,0], x[1,0]^2 + 3x[1,0], x[1,2]^2-x[2,2]^2]);
-------------------------------
[x[1,0]^2 + 3x[1,0], x[2,0] + x[1,1]^4]
-------------------------------
