Relative connections on Principal bundles and relative equivariant structures

Mainak Poddar, Anoop Singh

We investigate relative holomorphic connections on a principal bundle over a family of compact complex manifolds. A sufficient condition is given for the existence of a relative ho…

On pseudoeffective cones of projective bundles and volume function

Snehajit Misra, Anoop Singh

In this article, we compute the pseudo-effective cones of various projective bundles over higher dimensional varieties under some assumptions on as well a…

On the relative opers in dimension one

Anoop Singh, Abhitosh Upadhyay

We investigate the relative opers over the complex analytic family of compact complex manifolds of relative dimension one. We introduce the notion of relative opers arising from th…

On the relative logarithmic connections and relative residue formula

Snehajit Misra, Anoop Singh

We investigate the relative logarithmic connections on a holomorphic vector bundle over a complex analytic family. We give a sufficient condition for the existence of a relative lo…
