The purpose of this paper is to introduce new spaces and 0 that consist of all sequences whose Riesz transforms of order one are in the spaces and 0, respectively. We also show that and 0 are linearly isomorphic to the spaces and 0, respectively. The - and -duals of the spaces and 0 are computed. Furthermore, the classes (∶) and (∶) of infinite matrices are characterized for any given sequence space and determine the necessary and sufficient conditions on a matrix to satisfy −core()⊆−core(), −core()⊆−core() for all ∈ℓ∞
