Exact Euler Maclaurin formulas for simple lattice polytopes
Yael Karshon, Shlomo Sternberg, Jonathan Weitsman
Euler Maclaurin formulas for a polytope express the sum of the values of a function over the lattice points in the polytope in terms of integrals of the function and its derivative…
Euler Maclaurin with remainder for a simple integral polytope
Yael Karshon, Shlomo Sternberg, Jonathan Weitsman
We give an Euler Maclaurin formula with remainder for the sum of the values of a smooth function on the integral points in a simple integral polytope. This formula is proved by ele…
Maximal tori in the symplectomorphism groups of Hirzebruch surfaces
Yael Karshon
We count the conjugacy classes of maximal tori in the groups of symplectomorphisms of S^2 \times S^2 and of the blow-up of CP^2 at a point.
Complete invariants for Hamiltonian torus actions with two dimensional quotients
Yael Karshon, Susan Tolman
We study torus actions on symplectic manifolds with proper moment maps in the case that each reduced space is two-dimensional. We provide a complete set of invariants for such spac…
Centered complexity one Hamiltonian torus actions
Yael Karshon, Susan Tolman
We consider symplectic manifolds with Hamiltonian torus actions which are "almost but not quite completely integrable": the dimension of the torus is one less than half the dimensi…
Assignments and Abstract Moment Maps
Viktor L. Ginzburg, Victor Guillemin, Yael Karshon
moment maps arise as a generalization of genuine moment maps on symplectic manifolds when the symplectic structure is discarded, but the relation between the mapping and the action…
