Query: Twist deformations of Newtonian Schwarzschild-(Anti-)de Sitter classical
  system   In this article we provide three new twist-deformed Newtonian
Schwarzschild-(Anti-)de Sitter models. They are defined on the
Lie-algebraically as well as on the canonically noncommutative space-times
respectively. Particularly we find the corresponding Hamiltonian functions and
the proper equations of motion. The relations between the models are discussed
as well.
