Delzant's variation on Scott complexity
Gadde A. Swarup
We give an exposition of Delzant's ideas extending the notion of Scott complexity of finitely generated groups to surjective homomorphisms of finitely presented groups to finitely…
Regular Neighbourhoods and Canonical Decompositions for Groups
Peter Scott, Gadde Swarup
We find canonical decompositions for finitely presented groups which specialize to the classical JSJ-decomposition when restricted to the fundamental groups of Haken manifolds. The…
A proof of a homeomorphism theorem of Waldhausen
Siddhartha Gadgil, Gadde A. Swarup
We give a short proof of Waldhausen's homeomorphism theorem for orientable Haken 3-manifolds.
Canonical splittings of groups and 3-manifolds
Peter Scott, Gadde Swarup
We introduce the notion of a `canonical' splitting over Z or ZxZ for a finitely generated group G. We show that when G happens to be the fundamental group of an orientable Haken ma…
