Synopsis

Usage:

negativeSum C
Inputs:
- C, an instance of the type CurveClassRepresentativeM0nbar,
Outputs:
- an integer,

Description

This function sums the negative coefficients in an object of type CurveClassRepresentativeM0nbar. This is a measure of how far the expression is from being an effective sum of F curves.

i1 : L= { {{{2,1},{3},{4},{5}},-2}, {{{1,3},{2},{4},{5}},-7}, {{{1,4},{2},{3},{5}},1}};

i2 : C=curveClassRepresentativeM0nbar(5,L);

i3 : negativeSum C

o3 = -9
