: Some questions are coming up a few times (and I at least was
: quite on clear on some aspects), so here are a few clarifications:
: 1) If a function is convex, then any critical point (i.e. gradient
: equals 0) is a maximum: you do not need the Hessian test at that
: point.
Don't we need the Hessian test to determine if the function is convex or not?
Thanks
