In the 1960s, Almgren [3, 4] initiated a program to find minimal hypersurfaces in Riemannian manifolds using min-max method. This was largely advanced by Pitts [34] and Schoen–Simon [37] 1980s when manifold is compact without boundary. this paper, we finish for general with non-empty As corollary, establish existence of smooth embedded hypersurface free boundary any Euclidean domain.
