D.13.6.28 detropicalise
Procedure from library tropical.lib (see tropical_lib).
- Usage:
- detropicalise(f); f poly or f list
- Assume:
- if f is of type poly then t is a linear polynomial with
an arbitrary constant term and positive integer coefficients
as further coefficients;
if f is of type list then f is a list of polynomials of
the type just described in before
- Return:
- poly, the detropicalisation of f ignoring the constant parts
- Note:
- the output will be a monomial and the constant coefficient
has been ignored
Example:
| | LIB "tropical.lib";
ring r=(0,t),(x,y),dp;
detropicalise(3x+4y-1);
==> x3y4
