Hermite Reduction and Creative Telescoping for Hyperexponential Functions
Hermite reduction Hyperexponential function Telescoper
2013/9/3
We present a new reduction algorithm that simultaneously extends Hermite's reduction for rational functions and the Hermite-like reduction for hyperexponential functions. It yields a unique additive d...
On homotopy Poisson actions and reduction of symplectic Q-manifolds
homotopy Poisson actions reduction of symplectic Q-manifolds
2010/12/1
We present a general framework for reduction of symplectic Qmanifolds via graded group actions. In this framework, the homological structure on the acting group is a multiplicative multivector field.
