incInverse -- compute a flow in the preimage for a given weight

Synopsis

• Usage:

  incInverse(W, Q)

• Inputs:
  • W, a list, of integers, specifying the weight on each vertex
  • Q, an instance of the type ToricQuiver,

Description

i1 : Q = toricQuiver(bipartiteQuiver(2,3));

i2 : th = {-5,-1,2,2,2};

i3 : incInverse(th, Q)

o3 = {1, 2, 2, 1, 0, 0}
