Extending degree-2 Azumaya algebras with C2-actions and examples from character varieties of knot group
Justin Lawrence, Nicholas Rouse, Ben Williams
We give criteria to determine when a degree-2 Azumaya algebra with -action over a dense open subvariety of a curve extends to the entire curve as an algebra with -action.…
