Abstract. In my talk I will describe a relation between the 3-manifold invariant of Costantino--Geer--Patureau-Mirand, constructed from a non-semisimple category of representations of a quantum group, and counting of BPS states in a 6d (2,0) superconformal field theory compactified on a 3-manifold with a topological twist.
