Artin-Schreier Root Stacks and lifts of group actions

Sujoy Chakraborty, Souradeep Majumder

Let $G$ be a connected affine algebraic group defined over a field of positive characteristic. We prove that the action of $G$ on a smooth projective variety can be lifted to its a…

On positive cones of finite quotients of a normal variety

Ashima Bansal, Indranil Biswas, Souradeep Majumder

We study positivity properties of finite flat quotients of normal projective varieties. We show that the numerical groups and positive cones of these quotient varieties are related…

Positive Cones of the Projectivization of a parabolic vector bundle and Their Products over a Curve

Ashima Bansal, Indranil Biswas, Souradeep Majumder

We compute the positive cones of the projectivization of a parabolic vector bundle and the fiber product of two parabolic projective bundles over a smooth complex projective curve.…

Construction of the Moduli Space of Vector Bundles on an Orbifold Curve

Soumyadip Das, Souradeep Majumder

Let $k$ be an algebraically closed field of any characteristic, and let $(X, P)$ be an orbifold curve over $k$ . We construct the moduli space $\mathrm{M}_{(X,P)}^{\mathrm{ss}}(n, Δ)…

Orthogonal and Symplectic Parabolic Connections and Stack of Roots

Sujoy Chakraborty, Souradeep Majumder

Let $D$ be an effective divisor on a smooth projective variety $X$ over an algebraically closed field $k$ of characteristic $0$ . We show that there is a one-to-one correspondence b…

Rationality of moduli spaces of stable bundles on curves over $R$

Souradeep Majumder, Ronnie Sebastian

Let $C$ be a smooth, projective, geometrically irreducible curve defined over $R$ such that $C (R) = \emptyset$ . Let $r > 0$ and $d$ be integers which are coprime. L…

Parabolic bundles in positive characteristic

Manish Kumar, Souradeep Majumder

Algebraic parabolic bundles on smooth projective curves over algebraically closed field of positive characteristic is defined. It is shown that the category of algebraic parabolic…

Root stacks, principal bundles and connections

Indranil Biswas, Souradeep Majumder, Michael Lennox Wong

We investigate principal bundles over a root stack. In case of dimension one, we generalize the criterion of Weil and Atiyah for a principal bundle to have an algebraic connection.
