Hochschild cohomology parametrizes curved Morita deformations
Alessandro Lehmann
We show that, if one allows for curved deformations, the canonical map introduced in [KL09] between Morita deformations and second Hochschild cohomology of a dg algebra becomes a b…

Filtered derived categories of curved deformations
Alessandro Lehmann, Wendy Lowen
We propose a solution to the "curvature problem" from arXiv:1505.03698 and arXiv:0905.3845 for infinitesimal deformations. Let be a field, a dg algebra over and $A_n =…
