We prove a general criterion for the uniqueness of critical points of a functional in the presence of constraints such as positivity, boundedness, or fixed mass. Our method relies on convexity ...
A uniqueness theorem for the Cauchy problem for ordinary differential equations in complex Banach spaces is given. This paper generalizes and extends a number of known results. Journal Information ...
Nash equilibrium lies at the heart of game theory, representing a condition in which every participant chooses a strategy that optimises their individual outcome given the strategies of the others.
