Özet
Let G be a locally compact unimodular group with Haar measure rmdx and ω be the Beurling's weight function on G (Reiter, [10]). In this paper the authors define a space Ap,qω (G) and prove that Ap,qω (G) is a translation invariant Banach space. Furthermore the authors discuss inclusion properties and show that if G is a locally compact abelian group then Ap,qω (G) admits an approximate identity bounded in L1ω. (G). It is also proved that the space Lpω (G) ⊗L1ω L̄qω (G) is isometrically isomorphic to the space Ap,qω (G) and the space of multipliers from Lpω (G) to Lq′ω-1 (G) is isometrically isomorphic to the dual of the space Ap,qω (G) iff G satisfies a property Pqp. At the end of this work it is showed that if G is a locally compact abelian group then the space of all multipliers from L1ω (G) to Ap,qω (G) is the space Ap,qω (G).
