 Sep19 accepted Euler-Lagrange equation: Differentiation with respect to x Sep19 asked Euler-Lagrange equation: Differentiation with respect to x Sep19 comment Strong and weak extrema I feel like I follow and agree with everything you wrote. But it is exactly this that confuses me. When we add the stronger condition $P'$, we, as you noted, we eliminate some functions. Take a function that we eliminate. This function would then be within the neighborhood of the strong extrema, but not the weak one. How does that then imply the implication strong $\implies$ weak? In other words, it seems as if the weak extremum is "more of an extremum" than the strong one.

Of course, not going to explain this one to my student, but I like it.

Are you sure the bounds in the CVaR should not then be reversed, since I am dealing with a profit, rather than a loss density function?

Jun3 asked Calculating VaR, CVaR Jun3 comment Fair Value Of a Call Option Thank you very much. This question is a question from a past exam from a lecture and your answer seems to go beyond the scope of the lecture (don't get me wrong, it is perfectly understandable, I just cannot imagine a person that'd answer this, having only done the course, as we've never done anything like that and one would have to pull it out of thin air using a great deal of intuition). Thus I am wondering, are there perhaps any hidden assumptions or simplifications (even if they change the nature of the question a bit) that could've been made in a more rudimentary course?
