DA.DiffSupp

Computes the differential support of a differential polynomial.

Syntax

DA.DiffSupp(F:POLY):LIST

Description

Computes the differential support of the differential polynomial F.

  • @param F A differential polynomial.

  • @return The differential support of F.

Example

Use QQ[x[1..2,0..20]];
F:=x[1,4]^2-x[2,4]^3;
DA.DiffSupp(F);
