ToricQuiver _ List -- taking a subquiver by indexing

Synopsis

Operator: _
Usage:

Q_L
Inputs:
- Q, an instance of the type ToricQuiver,
- L, a list, of integers specifying which arrows to subset

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 the SeeAlso.
