Equivariant principal bundles over toric Deligne--Mumford stacks

Ramandeep Singh Arora, Chandranandan Gangopadhyay, Mainak Poddar

Let $\mathcal{X}(\mathbf{\Sigma })$ be the toric Deligne--Mumford stack with stacky torus $\mathcal{T}$ associated to the stacky fan $\mathbf{\Sigma }=(N,\Sigma ,\beta )$. A toric principal $H$-bu…
