ABSTRACT: Based on SU(3) flavor [SU(3)_f] symmetry, the irreducible SU(3)_f approach (IRA) and topological diagram approach (TDA) are both useful for the study of B_c—>BM and B_c—> B*M, where B_c and B(B*) denote the anti-triplet charmed baryon and octet (decuplet) baryon, respectively. In this talk, I would like to show that the IRA and TDA can be equivalent. Some phenomenological results will be given as well.
