In this paper, a general method is given of finding the commutatorgroup C(G) of a free product

G = A*B                    (1)

of two groups A and B having only the unit element 1 in common. The commutatorgroups C(A) and C(B) as well as the factorgroups A/C(A) and B/C(B) are supposed to be known.

Abstract


In this paper, a general method is given of finding the commutatorgroup C(G) of a free product

G = A*B                    (1)

of two groups A and B having only the unit element 1 in common. The commutatorgroups C(A) and C(B) as well as the factorgroups A/C(A) and B/C(B) are supposed to be known.
