    Kaledin obstruction classes and formality criteria
    Abstract: The formality of differential graded algebras over differential graded operads can be equivalently expressed in terms of the triviality of some Massey products. From this point of view, one can construct Kaledin classes which are obstruction classes to formality over any coefficient ring. This construction is closely related to pre-Lie deformation theory and generalizes to study formality in more general contexts, such as colored operads or properads. The aim of this talk is to present new formality criteria based on these classes.
