a generalization of the concept of the derivative of a function (strong derivative) for functions not assumed differentiable, but only integrable.
Examples
- 1.If two functions are weak derivatives of the same function, they are equal except on a set with Lebesgue measure zero, i.e., they are equal almost everywhere.
