Masaharu Kobayashi (Hokkaido University)

Let A^q_s(T) denote the space of all Lebesgue integrable functions on the torus T such that their Fourier coefficients belong to the weighted sequence spaces l^q_s(Z).  We consider necessary and sufficient conditions for all functions F in A^1_β(T) to operate on all real-valued functions in A^q_s(T).

This talk is based on a joint work with Enji Sato (Yamagata Univ.).
