Abstract
We define the sequence spaces [wθ,M,p,u,Δ]σ, [wθ,M,p,u,Δ]σ0, and [wθ,M,p,u,Δ]σ∞ which are defined by combining the concepts of Orlicz functions, invariant means,
and lacunary convergence. We also study some inclusion relations and linearity properties of the above-mentioned spaces. These are generalizations of those defined and studied by
Savaş and Rhoades in 2002 and some others before.
