“…The variable exponent analysis recently gains a lot of attentions [4,5,14,15,17,18,19,20,21,36,41,44,49,50,57,75] because the boundedness of several important linear operators in analysis, especially, the Hardy-Littlewood maximal operator, can be established for the variable Lebesgue spaces [14,17,19]. In addition, it provides a theoretical background on the studies of electrorheological fluid dynamics [1,2,61,63,64] and imaging processing [11].…”
