diffalg.LPot
the leading power of a differential polynomial
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 -------------------------------
