B-fields, quantization and Morita equivalence


This talk will discuss B-field symmetries of Poisson structures and their quantum counterpart. Using the deformation quantization of Poisson manifolds resulting from Kontsevich's formality theorem, we will show that, upon an integrality condition, B-field transformations classify Morita equivalent star products. This is based on joint work with V. Dolgushev and S. Waldmann.
