Title: Decision Problems for Fundamental Groups of 3-manifolds.

Abstract: the word problem for a group asks for an algorithm which 
can determine whether or not a given element in a group is trivial. 
Similarly the membership problem asks for an algorithm which can 
determine whether or not a given element lies in a given subgroup. 
We will discuss these two problems for the fundamental groups of 
3-manifolds. No previous knowledge of 3-manifold topology is required.
