Lie and homotopy methods in deformation theory
Differential graded Lie algebras, L-infinity algebras, obstruction theory, model categories.
Deformation theory is the study of small variations of algebro-geometric structures. It is a classical subject whose origin dates back to the works of Kodaira and Grothendieck . It is an intrisically difficult subject since it involves nonadditive structures and it can be reduced to an additive framework only in the infinitesimal setting.
Il the last 30 years a new powerful approach to deformation theory ofer a field of characteristic 0 has been proposed by Deligne, Drinfeld, Kontsevich and other by using methods and ideas from rational homotopy theory , homotopical algebra , differential graded Lie algebras [4,5] and L-infinity algebras .
