Unified SO(3)-quantum invariants for rational homology 3-spheres.

In 2001, K. Habiro constructed for an integer homology 3-sphere M a unified invariant I_M(q) which, if evaluated at any root of unity, gives the SU(2) Witten-Reshetikhin-Turaev invariant of M at that root. In this talk we extend Habiro's construction to rational homology 3-spheres. More precisely, given a rational homology 3-sphere M with |H_1(M;Z)|=b and an odd divisor c of b, we construct a unified invariant I_{M,c}(q), which dominates the SO(3) WRT invariants of M at all roots of unity whose order r has (r,b)=c.
