On function spaces with S-transform

  • Baby Kalita
  • Sunil Kumar Singh


For \(1 \le p,q <\infty \), we define the space \(W^{p,q}_{k_1,k_2}({\mathbb {R}}^n)\) by means of the S-transform where \(k_1\) and \(k_2\) are weight functions on \({{\mathbb {R}}^n}\) and \({\mathbb {R}}^n\times {\mathbb {R}}_0^n \), respectively. It is a Banach space with respect to a sum norm defined in this paper. Latter we discuss inclusion properties and obtain the dual space of \(W^{p,q}_{k_1,k_2}({\mathbb {R}}^n)\). Furthermore, we define the space \(\left( W^{p,q}_{k_1,k_2}\right) _{\xi }({\mathbb {R}}^n)\) where \(\xi \) is fixed and show that it is an essential Banach module over \(L^1_{k_1}({\mathbb {R}}^n)\).
