D.6.9.7 displayInvariants
Procedure from library hnoether.lib (see hnoether_lib).
- Usage:
- displayInvariants(INPUT); INPUT list or poly
- Assume:
INPUT is a bivariate polynomial, or the output of
develop(f) , resp. of extdevelop(develop(f),n) , or (one
entry of) the list of HN data computed by
hnexpansion(f[,"ess"]) .
- Return:
- none
- Display:
- invariants of the corresponding branch, resp. of all branches,
in a better readable form.
- Note:
- If the Hamburger-Noether expansion of the curve f is needed
for other purposes as well it is better to calculate this first
with the aid of
hnexpansion and use it as input instead of
the polynomial itself.
Example:

hnexpansion;
