Hl. Yao et Yr. Ping, REPRESENTATION TYPE OF ENDOMORPHISM ALGEBRAS OF EXCEPTIONAL SEQUENCESOF TYPE A(N), Acta Mathematica Sinica, New Series, 14(4), 1998, pp. 555-562
Let F be an algebraically closed field, <(Delta)over right arrow> be a
quiver of type A(n). In this paper we prove that the endomorphism alg
ebras of exceptional sequences over F<(Delta)over right arrow> are sum
s of finitely many tilted algebras of type A(m) where m less than or e
qual to n by using perpendicular categories, and thus the endomorphism
algebras of exceptional sequences of type A(n) are representation-fin
ite.
