Abstract

We consider the Witten-Reshetikhin-Turaev invariants or Chern-Simons partition function at or around roots of unity q=e2πi1Kq=e^{2\pi i \frac{1}{K}} with rational level K=rsK=\frac{r}{s} where rr and ss are coprime integers. From the exact expression for the G=SU(2)G=SU(2) Witten-Reshetikhin-Turaev invariants of Seifert manifolds at other roots of unity obtained by Lawrence and Rozansky, we provide an expected form of the structure of the Witten-Reshetikhin-Turaev invariants in terms of the homological blocks at other roots of unity. Also, we discuss the asymptotic expansion of knot invariants around roots of unity where we take a limit different from the standard limit in the volume conjecture.
