Summary
The theory of function spaces with variable exponents has been extensively studied by researchers since the work of Kovacǐ k and Rakosnık [1] appeared in 1991. In [2, 3] the authors defined the Herz-type Hardy spaces with variable exponent and gave some characterizations for them. In [2], the authors gave the definition of the Herz-type Hardy space with variable exponent HKqα(,⋅p)(Rn) and the atomic decomposition characterizations. (i) The homogeneous Herz-type Hardy space with variable exponent HKqα(,⋅p)(Rn) is defined by HKqα(,⋅p) (Rn) (17). (ii) The nonhomogeneous Herz-type Hardy space with variable exponent HKqα(,⋅p)(Rn) is defined by HKqα(,⋅p) (Rn) (19). Weighted Lq norm and weak(1,1) estimates were established by Chanillo in [13] The boundedness of these operators on the weighted Herz-type. Motivated by [2, 14], we will study the boundedness of the strongly singular convolution operators Tb on Herz-type Hardy spaces with variable exponent.
