May 16,  · Moreover, applying this, together with a new Cotlar-type inequality, the authors show that if the Calderón–Zygmund operator T is bounded on L2 (μ), then the corresponding maximal Calderón–Zygmund operator is bounded on Lp (μ) for all p ∈ (1, ∞), and bounded from L1 (μ) into L1,∞ (μ). These results essentially improve the existing results. Alberto Pedro Calderón (September 14, – April 16, ) was an Argentinian Analysis" (sometimes simply known as the "Calderón-Zygmund School").
