The Direct Method in the calculus of variations is a powerful approach used to find the extrema (minima or maxima) of functionals, which are mappings from a space of functions to the real numbers. This method primarily involves establishing the existence of a solution to a variational problem and typically uses concepts from analysis, compactness, and weak convergence.
