DA.LPot

Computes the leading power of a differential polynomial.

Syntax

DA.LPot(F:POLY):POLY

Description

DA.LPot returns the leading power of polynomial F wrt. the current differential term order, or the hereby induced ranking respectively.

  • @param F A differential polynomial.

  • @return The leading power of F.

Example

Use Q[x[1..2,0..20]];
Use Q[x[1..2,0..20]], Ord(DA.DiffTO("Lex"));
DA.LPot(x[1,1]^2x[1,2]^2 + 1/4x[1,2]);
-------------------------------
x[1,2]^2
