Journal of Algebra, Amsterdã, v. 289, n. 1, p. 20-41, July 2005.e- 0021-8693http://repositorio.bc.ufg.br/handle/ri/19279Let k be an algebraically closed field and A be a tree algebra. We consider here a class obtained by the blowing-up of a tree algebra A at a set of vertices D of A, such an algebra is denoted by . The objective of this paper is to prove the equivalence between the derived-tameness and the non-negativity of the Euler form for algebras of this form. We also show that, in this case, if D is a non-empty set then must be derived equivalent to a special incidence algebra, called semichain algebra.engAcesso AbertoTame derived categoryEuler formBlowing-up of algebraTree algebraArtigo10.1016/j.jalgebra.2005.02.019
