Spectral orders, uniform integrability and Lebesgue's dominated convergence theorem

Kong Ming Chong
1974 Transactions of the American Mathematical Society  
Using the 'spectral' order relations < and -K introduced by Hardy, Littlewood and Pólya, we characterize the uniform integrability of a family of integrable functions. We also prove an extension and a 'converse' of the classical Lebesgue's dominated convergence theorem in terms of the 'spectral' orders < and •«.
