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