Nội dung: Deformation theory for geometric objects was first studied by K. Kodaira and A. Grothendieck in the 1950's. A similar deformation theory for (non-commutative) algebras was introduced and studied completely by Murray Gerstenhaber in his seminal papers in 1963-1964. In this seminar, I will talk mainly about Gerstenhaber's deformation theory and its generalizations in some contexts. In particular, deformation theory of presheaves and the L-infinity structure on the Gertenhaber-Schack complex will be presented.
