In analysis on the real vector space R , the Hardy space H (for 0 < p ≤ ∞) consists of tempered distributions f such that for some Schwartz function Φ with ∫Φ = 1, the maximal function is in L (R ), where ∗ is convolution and Φt (x) = t Φ(x / t). The H -quasinorm f Hp of a distribution f of H is defined to be the L norm of MΦf (this depends on the choice of Φ, but different choices of Schwartz functions Φ give equivalent norms). The H -quasinorm is a norm when p ≥ 1, but not … In harmonic analysis in mathematics, a function of bounded mean oscillation, also known as a BMO function, is a real-valued function whose mean oscillation is bounded (finite). The space of functions of bounded mean oscillation (BMO), is a function space that, in some precise sense, plays the same … See more According to Nirenberg (1985, p. 703 and p. 707), the space of functions of bounded mean oscillation was introduced by John (1961, pp. 410–411) in connection with his studies of mappings from a bounded set Ω belonging to R into … See more BMO functions are locally p–integrable BMO functions are locally L if 0 < p < ∞, but need not be locally bounded.
