Talk:Convex function/to do
- Resolve notation conflict: same style X for the domain and for a random variable.
- Improve notation: use either x1, x2 or x, y for variables throughout the text.
- Add valid references for the properties.
- Remove redundant repetition of properties for a function of a scalar and vector arguments (perhaps by putting them into a single list and avoiding explicit mention whether the domain is R^n or R, as it is done in the definition)
