In How Many Ways Can We Define Derivatives?

75 Views Asked by At

On real and complex manifolds, we can define derivatives either by limits, or by Lie brackets, or by product rule: $$ (uv)'=u'v+v'u $$

I wonder if there's other ways to define derivatives. They may not be on just manifolds, but also other structures.

You may be looking for derivations, which generalize the properties of a derivative to a linear map on an algebra over a field.
