Bounded Mean Oscillation (BMO) is a function space used in the field of harmonic analysis and is particularly important in the study of partial differential equations, complex analysis, and real analysis. A function \\( f \\) defined on a domain (often \\( \\mathbb\{R\}^n \\)) is said to belong to the BMO space if its mean oscillation over all balls (or spheres) in the domain is bounded.
