We prove that the Chang’s group of the MV-center of any BL-algebra L is a direct summand in the above group. We also find a direct description of the complement of the Chang’s group of the MV-center in terms of the filter of dense elements of L. Finally, we compute some examples of the introduced group.Keyphrases: bl algebra, good sequence, l group, mv algebra, o group In: Nikolaos Galatos, Alexander Kurz and Constantine Tsinakis (editors).
