This function creates a tropical cycle from a fan and a list of multiplicities. The multiplicities must be given in the same order as the maximal cones appear in the MaximalCones list.
i1 : F = fan {posHull matrix {{1},{0},{0}}, posHull matrix {{0},{1},{0}}, posHull matrix {{0},{0},{1}}, posHull matrix {{-1},{-1},{-1}}} o1 = F o1 : Fan |
i2 : mult = {1,2,-3,1} o2 = {1, 2, -3, 1} o2 : List |
i3 : tropicalCycle(F, mult) o3 = TropicalCycle{...2...} o3 : TropicalCycle |
The object tropicalCycle is a method function.
