In particular, we give partial solutions to a conjecture of Power [Limit Algebras, Longman, 1992, Notes to Chapter 8] and to an open problem [op. cit., Problem 7.8]. As a further consequence, we describe epimorphisms between various classes of limit algebras.13 pagesOperator AlgebrasFunctional Analysis47D25 (Primary) 46K50, 46H40 (Secondary)text
