Abstract: The Habiro ring first appeared in work of Habiro where he showed that there is a unified Witten-Reshetikhin-Turaev (WRT) sl2 invariant of integral homology 3-spheres with values in the Habiro ring. The Habiro ring has attracted attention of number theorists (Manin, Marcolli, ...) who suggest that the Habiro ring can be considered as the ring of regular functions on the elusive ”field with 1 element”. In the talk we will explain the Habiro ring and show that for any simple Lie algebra there is a unified quantum invariant of integral homology 3-spheres with values in the Habiro ring that reduces to the WRT invariant at roots of unity. This isjoint work with Habiro.
