Abstract: In 1908, Tietze posed the provocative question of whether a mathematical knot 
- a knotted rope, with its ends spliced together - is completely determined by the 
topological shape of the empty space that surrounds the knot. After being open for 80 
years, this question was solved in 1988, and we know the answer is Yes.

Since that time, mathematicians have studied the open question of whether the same 
property holds for knots in general 3-dimensional spaces. Given a 3-dimensional manifold 
M, is a knot in M entirely determined by the space that surrounds it in M? I will 
discuss some recent work on this question using hyperbolic (negatively curved) geometry. 
This is joint work with Jessica Purcell and Saul Schleimer.
