Abstract: | Scott (1978) 12] showed Seifert 3-manifold groups are subgroup separable. Niblo (1992) 9] improved this result by showing that these groups are double coset separable. In Allenby, Kim and Tang (2005) 2] it was shown that all but two types of groups in the orientable case are conjugacy separable. Martino (2007) 7] using topological results showed that Seifert groups are conjugacy separable. Here we use algebraic method to show that Seifert groups over non-orientable surfaces are conjugacy separable. |
