 Intrinsic square functions on functions spaces including weighted Morrey spaces Bull. Korean Math. Soc. 2013 Vol. 50, No. 6, 1923-1936 https://doi.org/10.4134/BKMS.2013.50.6.1923Published online November 1, 2013 Justin Feuto Universit\'e de Cocody Abstract : We prove that the intrinsic square functions including Lusin area integral and Littlewood-Paley $g^{\ast}_{\lambda}$-function as defined by Wilson, are bounded in a class of function spaces include weighted Morrey spaces. The corresponding commutators generated by $BMO$ functions are also considered.
