Oberseminar Algebra und Geometrie: Severin Barmeier: Diagrams of algebras, their deformations and applications to geometry
am Mittwoch, 14.11.2018 16:15 im Raum M6
We recall the notions of diagrams of algebras and their deformations given in the seminar of the previous week. We give further details about the construction of an L-infinity structure on the Gerstenhaber-Schack complex, controlling the higher deformation theory of diagrams of algebras. We will illustrate the theory with explicit examples for certain non-compact complex surfaces.
