✦ Synopsis


Let (A) be a finite-dimensional algebra over an algebraically closed field. If (A) is an (\mathscr{F}(\Delta))-finite quasi-hereditary algebra, then the endomorphism algebra of the direct sum of all non-isomorphic indecomposable (\Delta)-good modules over (A) is quasi-hereditary. Moreover, this endomorphism algebra is left QF-3 if and only if the injective direct summand of the characteristic module (T) cogenerates (T).
