Moduli Stacks of Bundles on Local Surfaces

Oren Ben-Bassat, Elizabeth Gasparim

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


We give an explicit groupoid presentation of certain stacks of vector bundles on formal neighborhoods of rational curves inside algebraic surfaces. The presentation involves a Möbius type action of an automorphism group on a space of extensions.
