diffalg.LPot

Returns the leading power of F with respect to the current differential term ordering.

Syntax

$diffalg.LPot(F:POLY):POLY

Description

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

Example

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