We establish 14 fundamental theorems that character- ize norm attainment in terms of strict convexity, uniform convexity, and weak con- vergence. We explore the duality structure of Orlicz spaces, highlighting key differ- ences from Lp spaces and providing a variational characterization of the norm. We also discuss applications in optimization and variational problems, demonstrating the significance of norm-attaining functionals in these settings. Our findings con- tribute to a deeper understanding of Orlicz space geometry and its implications for functional analysis and applied mathematics.
