Normal Surface Q-Theory
Abstract:
We describe an approach to normal surface theory for
triangulated 3-manifolds which uses only the quadrilateral disk
types (Q-disks) to represent a nontrivial normal surface.
Just as with regular
normal surface theory, interesting surfaces are among those associated
with the vertices of the projective solution space of this
new Q-theory.
