Abstract:
We obtain both necessary and sufficient conditions for the free product of two groups with normal amalgamated subgroups to be a residually C-group, where C is a root class of groups, which must be homomorphically closed in most cases.
Keywords:
generalized free product, residual property, root class of groups.
