Title:
Algebraic symplectic reduction for the additive group

Abstract:
Algebraic symplectic reduction is a method for constructing quotients of 
algebraic group actions on algebraic symplectic varieties, such that the 
quotients are also algebraic symplectic. We will overview how moment 
maps and geometric invariant theory for reductive groups is used to 
perform the reduction, give some examples, and describe how to construct 
algebraic symplectic analogues of reductive group quotients. We will 
give some motivation for studying non-reductive group and explain some 
new results for the additive group.
