Unoriented topological quantum field theory and link homology
arXiv:math/0506229 · doi:10.2140/agt.2006.6.1069
Abstract
We investigate link homology theories for stable equivalence classes of link diagrams on orientable surfaces. We apply (1+1)-dimensional unoriented topological quantum field theories to Bar-Natan's geometric formalism to define new theories for stable equivalence classes.
