Abstract
Given1≤p,q≤∞and sequences of integers(nk)kand(nk′)ksuch thatnk≤nk′≤nk+1, the generalized mixed norm spaceℓℐ(p,q)is defined as those sequences(aj)jsuch that((∑j∈Ik|aj|p)1/p)k∈ℓqwhereIk={j∈ℕ0 s.t. nk≤j<nk′},k∈ℕ0. The necessary and sufficient conditions for a sequenceλ=(λj)jto belong to the space of multipliers(ℓℐ(r,s),ℓ𝒥(u,v)), for different sequencesℐand𝒥of intervals inℕ0, are determined.
