SO(3) invariants of Seifert manifolds and their algebraic integrality

Bang-He Li

For Seifert manifold $M=X({p_1}/_{\f{q_1}},{p_2}/_{\f{q_2}}, ...,{p_n}/_ {\f{q_n}}), τ^{'}_r(M)$ is calculated for all $r$ odd $\geq 3$ . If $r$ is coprime to at least $n - 2$ of $p_k…

An example concerning Ohtsuki's invariant and the full SO(3) quautum invariant

Bang-He Li, Tian-Jun Li

Two lens spaces are given to show that Ohtsuki's $τ$ for rational homology spheres does not determine Kirby-Melvin's ${τ_{r}^{^{'}}, r o dd \geq 3}$

Kirby-Melvin's $τ_{r}^{^{'}}$ and Ohtsuki's $τ$ for Lens spaces

Bang-He Li, Tian-Jun Li

In this note, we first derive explicit formulas for Kirby-Melvin's three-manifold invariants $τ_{r}^{^{'}}$ for all Lens spaces from our results for another set of invariants $ξ_{r}$ defi…
