For a smooth projective variety, Deligne and Illusie proved that the Hodge-to-de Rham spectral sequence degenerates at the first page. For singular varieties, this classical picture no longer holds. In this talk, I will discuss what happens for integral projective curves with local complete intersection singularities. I will explain that the derived Hodge-to-de Rham spectral sequence degenerates at the second page exactly when all singularities are quasihomogeneous plane curve singularities.
