Degeneration of (noncommutative) Hodge to de Rham spectral sequence of elliptic curves
For a smooth projective variety, Deligne and Illusie showed that its Hodge to de Rham spectral sequence degenerates at the first page. During this talk, I will talk about a special nonsmooth case, the projective nodal cubic curve. In particular, we will see that its Hodge to de Rham spectral sequence degenerates at the second page. I will also discuss why this is important for computation of categorical enumerative invariants of nodal curve.
