Here Lambda is a non-empty set of indices, 0 is an accumulation point of Lambda and vertical bar s - t vertical bar(lambda) denotes the non-isotropic distance between the points s, t is an element of R-n.eninfo:eu-repo/semantics/closedAccessNonlinear Singular IntegralNon-Isotropic DistanceLipschitz ConditionArticle602267275WOS:000453592700012N/A
