Can you provide a proof or explanation as to why a critical point found using the Lagrange multipliers method cannot be a saddle point if the set is both closed and bounded?
I've so a post explaining that it can't but I'm interested in proof.

Proof that a critical point found by Lagrange multipliers method can't if set is closed and bounded be a saddle point?
