On torsion-freeness of Kähler differential sheaves
Nilkantha Das, Sumit Roy
Let be a normal algebraic variety over an algebraically closed field of characteristic zero. We prove that the Kähler differential sheaf of is torsion-free if and only…

On Endomorphism of Algebraic Varieties
Nilkantha Das
We prove that a quasi-finite endomorphism of an algebraic variety over an algebraically closed field of characteristic zero, that is injective on the complement of a closed subvari…

Elliptic Gromov-Witten Invariants of Del-Pezzo Surfaces
Chitrabhanu Chaudhuri, Nilkantha Das
We obtain a formula for the number of genus one curves with a variable complex structure of a given degree on a del-Pezzo surface that pass through an appropriate number of generic…
