We first study the
Chern–Simons partition function of orthogonal quantum group invariants and
then propose a new orthogonal Labastida–Mariño–Ooguri–Vafa (LMOV)
conjecture as well as a degree conjecture for free energy associated to the
orthogonal Chern–Simons partition function. We prove the degree conjecture and
some interesting cases of the orthogonal LMOV conjecture. In particular, we
provide a formula of the colored Kauffman polynomials for torus knots and
links, and applied this formula to verify certain cases of the conjecture at
roots of unity except 1. We also derive formulas of Lickorish–Millett type
for Kauffman polynomials and relate all these to the orthogonal LMOV
conjecture.
