Oberseminar: Algebra und Geometrie: Severin Barmeier: Diagrams of algebras, categories of coherent sheaves and deformations
Wednesday, 07.11.2018 16:15 im Raum M6
Diagrams of algebras arise naturally by restricting the structure sheaf of a smooth variety to a cover of affine open sets.
Given a diagram of algebras obtained in this way, its deformations correspond to deformations of the Abelian category of (quasi)coherent sheaves. We give explicit examples of such deformations via L-infinity algebras and explain the connection to "classical" deformations and deformation quantizations.
