- I was reading Kaufmann's book on knots the other day and I have a
- question for the experts out there. I understand that the q-state potts
- model partition function is actually a invariant polynomial. My
- question is that given any lattice system...is the partition function
- a invariant polynomial(like the jones or HOMFLY etc.)? If not, when
- is it possible. Also I have another naive question...When one writes
- down the invariant polynomial for a certain knot e.g. the jones
- polynomial, V(t), what is the variable t? I understand that V(t) is
- invariant under "nice" topological deformations of the knot. I am
- asking this because in an actual physical system where you have knots
- does the variable t correspond to some physical parameter. I may be
- completely off on both questions and would appreciate it if someone
- explained it to me. thanks
