Instantons with continuous conformal symmetries: Hyperbolic and singular monopoles and more, oh my!
C. J. Lang
Throughout this paper, we comprehensively study instantons with every kind of continuous conformal symmetry. Examples of these objects are hard to come by due to non-linear constra…

The topological space of the stack of -zips can be computed using a refinement process. We extend this refinement process to a more general framework and show that in many situa…

Perverse sheaves on the stack of -zips
Christopher Lang
We explain how to compute simple perverse sheaves on the stack of -zips and do these computations in several examples.
