    Study of some boundary value problems using variational methods
    (Mohamed Boudiaf University of M’sila, Faculty of Mathematics and Computer Science, Department of Mathematics, 2024-06) DILMI, Ikram; FERAHTIA, Nassim: Supervisor
    In this dissertation, we studied some boundary problems using variational methods, where we gave a variational formulation of this problem, then we used the Lax-Milgram theorem to demonstrate the existence and uniqueness of the solution, i.e., if we have a mathematical problem the classic formulation consists to search for a solution function of this problem.
