SUBGROUP SEPARABILITY OF GRAPHS OF FREE GROUPS WITH CYCLIC EDGE GROUPS

It is shown that Jrl of a finite graph of free groups with cyclic edge groups is subgroup separable unless Jrl has a non-trivial element g such that gn "V gm with n i= ±m. It is easy to decide from the presentation if such a conjugacy exists.
