ToricQuiver _ List -- taking a subquiver by indexing

Operator: _
Usage:

Q_L
Inputs:
- Q, a toric quiver,
- L, a list, of integers specifying which arrows to subset
Outputs:
- S, a toric quiver, the subquiver in question

Description

This method returns a the subquiver of the quiver Q that is made up of the arrows in the list L. Note that this method re-orders the subquiver labels to create a standalone quiver. To retain the original quiver labels on the subquiver, see (symbol ^, ToricQuiver, List).

i1 : Q = bipartiteQuiver(2, 3);

i2 : SQ = Q_{0,1,3}

o2 = ToricQuiver{flow => {1, 1, 1}              }

                                    | 0  1  0  |
                 Q0 => {0, 1, 2, 3}
                 Q1 => {{0, 2}, {0, 3}, {1, 2}}
