摘要：The frieze variety, introduced by Lee, Li, Mills, Schiffler and Seceleanu for providing a geometric interpretation of the acyclic quiver as well as concrete numerical invariants, is the smallest algebraic variety containing points obtained from the frieze pattern. Lee, Li, Mills, Schiffler and Seceleanu proved that the dimension of the frieze variety of an acyclic quiver is equal to 0, 1 or ≥ 2 if and only if the quiver is representation finite, tame, or wild, respectively. Igusa and Schiffler introduced a generalized version of the frieze variety. In this talk, we study the generalized frieze variety associated with a cluster automorphism. For affine quivers, we show every component of the frieze variety is a rational curve.
