Derived Hodge-to-de Rham Degeneration and Quasihomogeneous Curve Singularities

Yunfan He, Junxiao Wang

We study the Hodge-completed derived Hodge-to-de Rham spectral sequence of integral projective complex curves. We prove E2-degeneration whenever every singularity is analytically q…

Hodge to de Rham degeneration of nodal curves

Yunfan He

We compute the Hochschild and negative cyclic homology of the nodal curves, and we show that the (noncommutative) Hodge to de Rham spectral sequence degenerates at the second page.…
