The curvature problem for formal and infinitesimal deformations

11 Sep 2015 Lowen Wendy Bergh Michel Van den

We interpret all Maurer-Cartan elements in the formal Hochschild complex of a small dg category which is cohomologically bounded above in terms of torsion Morita deformations. This solves the "curvature problem", i.e. the phenomenon that such Maurer-Cartan elements naturally parameterize curved A_infinity deformations... (read more)
