Abstract

In a beautiful paper Deligne and Illusie proved the degeneration of the Hodge-to-de Rham spectral sequence using positive characteristic methods. Later Kato generalized their results to logarithmic schemes. In the talk I give a geometric interpretation of Kato's result using derived intersections generalizing a result of Arinkin, Caldararu and myself.
