Realizations of Frobenius functions
In an earlier paper (Agoston et al., CMS Conf: Proc. 18 (1996), 17-37) we studied the so-called Frobenius functions on certain translation quivers. Here we show that the classification given there is in some sense complete: every Frobenius length function on the wing W(n) and the tube T(n) is equivalent to the length function on a convex subquiver of the Auslander-Reiten quiver of the module category over some algebra A.
