Hodge-to-de Rham degeneration and quasihomogeneous singularities of curves
Yunfan He
We study the Hodge-to-de Rham spectral sequence for integral projective curves with local complete intersection singularities. We prove that degeneration at the E2-page is equivale…

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.…
