Noncommutative and Quantum Gravity Theories

A geometrical way to calculate N-point Feynman diagrams is reviewed. As an example, the dimensionally regulated three-point function is considered, including all orders of its ɛ-expansion. Analytical continuation to other regions of the kinematical variables is discussed.
