摘要: The space BMO of functions of  bounded means oscillations, as well as its  generalization, the John-Nirenberg spaces  $JN_p$, were introduced by John and Nirenberg  in their celebrated article [Comm. Pure Appl.  Math. 14 (1961), 415-426], and have found  various applications in mathematics. It is  known that the limit space of $JN_p$ as $p \to\infty$ is just BMO. In recent years,  there exists an increasing interest in  John--Nirenberg spaces and some of their  variants and generalizations. In this talk,  we introduce some recent progress on  John--Nirenberg spaces and their various variants.
