Characterizing Residual Finiteness of Tubular Groups.
A tubular group is a group that splits as a graph of groups where all edge groups are Z and all vertex groups are ZxZ. There are many interesting examples of tubular groups exhibiting subtle and pathological behaviour. In my talk I will characterize the f.g. tubular groups that are residually finite. This is (ongoing) joint work with Daniel Woodhouse.
