Title: Hochschild cohomology of Brauer-Severi varieties in positive characteristic.

Abstract: Deformation quantization in positive characteristic yields natural examples of Azumaya algebras whose Hochschild cochain complexes are not formal. In this work in progress we show that even though formality fails for these algebras, formality holds for the corresponding Brauer-Severi varieties.
