Local $\nu$-Euler Derivations and Deligne's Characteristic Class of Fedosov Star Products and Star Products of Special Type

Nikolai Neumaier

In this paper we explicitly construct local $\nu$-Euler derivations $\mathsf E_α= ν\partial_ν+ \Lie{ξ_α} + \mathsf D_α$, where the ${\xi }_{\alpha }$ are local, conformally symplectic vector fiel…
