Behavior of the extended complexity of irreducible 3-manifolds
O. N. Shatnykh Kurgan State University
Abstract:
We construct the extended complexity of irreducible 3-manifolds; unlike the usual complexity [1] it is not an integer, but an ordered tuple of five integers. The benefit of extended complexity is that it always decreases when a manifold is cut along some incompressible boundary incompressible surface.
Keywords:
3-manifold, spine, complexity.
