Given a 1-dimensional diffusion, singular or not, a complete description of its generator G is now before us. G coincides on its domain with a differential operator G• of degree ≦2 expressed in terms of invariants (scale, speed measure, etc.) via the formulas 4.1.8) [or 4.1.31,32,33)] and each invariant has a simple probabilistic meaning embodied in the formulas 4.1.7) [or 4.1.22, 23 b, 23 c, and 26)].
