This function checks if a tropical cycle is balanced.
i1 : QQ[x,y,z] o1 = QQ[x..z] o1 : PolynomialRing |
i2 : V = tropicalVariety(ideal(x+y+z)) o2 = V o2 : TropicalCycle |
i3 : isBalanced V o3 = true |
i4 : F = fan {posHull matrix {{1},{0},{0}}, posHull matrix {{0},{1},{0}}, posHull matrix {{0},{0},{1}}, posHull matrix {{-1},{-1},{-1}}} o4 = F o4 : Fan |
i5 : mult = {1,2,-3,1} o5 = {1, 2, -3, 1} o5 : List |
i6 : isBalanced (tropicalCycle(F, mult)) o6 = false |
The object isBalanced is a method function.
