We also prove the direct and inverse theorems in these spaces.eninfo:eu-repo/semantics/openAccessweighted grand variable exponent LebesgueSobolev and Lipschitz spacemaximal operatormodulus of smoothnessbest approximationJackson and inverse theoremsK-functionalWeighted variable exponent grand Lebesgue spaces and inequalities of approximationArticle50119921510.15672/hujms.6839972-s2.0-85101165141Q2492628WOS:000640068900018Q2
