Equivaraint principal bundles over toric DM stacks

We extend the classification of torus equivariant framed principal bundles over toric varieties using Tits buildings by Kaveh, Mannon, and Huang to such bundles over toric Deligne-Mumford stacks. A corollary is that any such bundle over a stacky projective line splits. This is a joint work with Chandranandan Gangopadhyay and Ramandeep Singh Arora.
