Baumslag's conjectures for one-relator groups with torsion

Let $G=\langle A\mid w^n=1\rangle$ be a finitely generated one-relator group with torsion.

Baumslag's conjectures.

1. $G$ is residually finite.
2. $G$ is virtually free-by-cyclic.
3. $G$ is coherent.

These conjectures concern the expected good structural and finiteness properties of one-relator groups with torsion. They were posed by Gilbert Baumslag in connection with the study of the torsion case of one-relator groups; the supplied source does not establish whether they are resolved.
