A ring is -dimensional if it is hereditary and noetherian, or equivalently if every submodule of a f.g. projective -module is f.g. projective.
The FIN (Fontes-Isopi-Newman) singular diffusion .
Let be a standard one-dimensional Brownian Motion, and l( , ) its local time at . Define the random time-change:
and its inverse
Then the FIN singular diffusion is
We say that a symmetric multicategory is freely symmetric if and only if for every arrow and permutation
