Abstract
In this chapter we prove two further important transfer theorems for the compressed word problem:
-
The compressed word problem for a multiple HNN-extension of a base group H over finite associated subgroups is polynomial time Turing-reducible to the compressed word problem for H.
-
The compressed word problem for an amalgamated product of group H 1 and H 2 with finite amalgamated subgroups is polynomial time Turing-reducible to the compressed word problems for H 1 and H 2.
