An Equisingular Specialisation of the Compactified Jacobian and its applications
Sourav Das, A. J. Parameswaran, Subham Sarkar
For any positive integer , let be a projective irreducible nodal curve with nodes. We show that the Betti numbers and the mixed Hodge numbers of the compactified Jacob…

A Torelli Type theorem for Nodal curves
Suratno Basu, Sourav Das
The moduli space of Gieseker vector bundles is a compactification of moduli of vector bundles on a nodal curve. This moduli space has only normal crossing singularity and it provid…

Relative Log-Symplectic structure on a semi-stable degeneration of moduli of Higgs bundles
Sourav Das
In a recent paper \cite{3}, a semi-stable degeneration of moduli space of Higgs bundles on a curve has been constructed. In this paper, we show that there is a relative log-symplec…
