quiver

  • quiver = finite oriented graph without loop and 2-cycle



quiver mutations

  • This is a process that can be done at any point of the quiver
  • The new quiver has same points as the old quiver.
  • Arrows into the point of mutation in the old quiver becomes arrows out, in the new quiver.
  • Arrows out of the point of mutation in the old quiver becomes arrows into, in the new quiver.
  • There are new arrows formed. Any path of length 2 through the point of mutation gives an arrow in the new quiver. The arrow has the same startining and ending points as the path.
  • The new arrows simplify with any old arrows in the opposite direction.
