Group actions on stacks and applications
We provide the correct framework for the treatment of group actions on algebraic stacks (including fixed points and quotients). It is then used to exploit some natural actions on moduli stacks of maps of curves. This leads to the construction of a nice desingularization of the normal stack of curves with level structures considered by Deligne and Mumford ([DM]), and to a presentation of stacks ...
متن کاملA note on group actions on algebraic stacks
we give the basic definitions of group actions on (algebraic) stacks, and prove the existence of fixed points and quotients as (algebraic) stacks.
متن کاملGroup Actions on Quiver Varieties and Applications
We study algebraic actions of finite groups of quiver automorphisms on moduli spaces of quiver representations. We decompose the fixed loci using group cohomology and we give a modular interpretation of each component. As an application, we construct branes in hyperkähler quiver varieties, as fixed loci of such actions.
متن کاملHamiltonian Group Actions on Symplectic Deligne-mumford Stacks and Toric Orbifolds
We develop differential and symplectic geometry of differentiable Deligne-Mumford stacks (orbifolds) including Hamiltonian group actions and symplectic reduction. As an application we construct new examples of symplectic toric DM stacks.
متن کاملSmooth Gluing of Group Actions and Applications
Let M1 and M2 be two n-dimensional smooth manifolds with boundary. Suppose we glue M1 and M2 along some boundary components (which are, therefore, diffeomorphic). Call the result N. If we have a group G acting continuously on M1, and also acting continuously on M2, such that the actions are compatible on glued boundary components, then we get a continuous action of G on N that stitches the two ...
