Towards the Generalized Purely Wild Inertia Conjecture for product of Alternating and Symmetric Groups
Soumyadip Das
We obtain new evidence for the Purely Wild Inertia Conjecture posed by Abhyankar and for its generalization. We show that this generalized conjecture is true for any product of sim…
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…
Torus quotients of Schubert varieties in the Grassmannian
S. Senthamarai Kannan, Arpita Nayek, Pinakinath Saha
Let and be a maximal torus of where is a positive even integer. In this article, we study the GIT quotients of the Schubert varieties in the Gra…
Non-globally generated bundles on curves
John Kopper, Sayanta Mandal
We describe the locus of stable bundles on a smooth genus curve that fail to be globally generated. For each rank and degree with , we exhibit a component…

S. Senthamarai Kannan, Pinakinath Saha
Let be a simple algebraic group of adjoint type over whose root system is of type Let be a maximal torus of and be a Borel subgroup of co…
Parabolic subgroups and Automorphism groups of Schubert varieties
S. Senthamarai Kannan, Pinakinath Saha
Let be a simple algebraic group of adjoint type over the field of complex numbers, be a Borel subgroup of containing a maximal torus of Let be…
