We prove that a power series invariant of suitable ideal
triangulations, defined by Frohman-Kania-Bartoszynska coincides with
the power series invariant of Dimofte-Gaiotto-Gukov known as the 3D
index. In partucular, we deduce that the FKB invariant is topological,
and that the tetrahedron weight of the 3D index is a limit of quantum
6j symbols. Joint work with Roland van der Veen.
