Abstract

This paper collects some results from [AFM] and from [AM]. Our purpose is to illustrate some interesting classes of algebras which generate the whole variety of BL-algebras. In particular, we prove that such variety is generated by its finite members and by the class of finite ordinal sums of Lukasiewicz t-norm algebras. Finally, we characterize the BL-chains which generate the whole variety of BL-algebras.
