Based on a shift operator, we consider the subspace Gp) (??, ?) of the space Lp) (??, ?), where continuous functions are dense, and the boundedness of the singular operator in this subspace is proved. We establish the basicity of exponential system {e int}n?Z for Gp) (??, ?) and the basicity of trigonometric systems {sin nt}n?N and {cos nt}n?N0 for Gp) (0, ?).eninfo:eu-repo/semantics/openAccessgrand Lebesgue space, exponential system, minimality, density, basisArticleQ3WOS:0008899246000061163008N/A2-s2.0-8514185817310.15672/hujms.1076849
