Abstract
In this paper, we analyze various classes of weighted Stepanov ergodic spaces, weighted Weyl ergodic spaces and weighted pseudo-ergodic spaces in \({{\mathbb {R}}}^{n}\) with the help of results from the theory of Lebesgue spaces with variable exponents \(L^{p(x)}\). Several structural results of ours seem to be new even in the case of consideration of the constant exponents \(p(x)\equiv p\in [1,\infty ).\) We especially examine the Stepanov asymptotical almost periodicity at minus infinity and the Weyl asymptotical almost periodicity at minus infinity, providing also some interesting applications to the abstract Volterra integro-differential equations in Banach spaces.
