Asymptotically Weyl almost periodic functions in Lebesgue spaces with variable exponents

Abstract

In this paper, we introduce and analyze several different notions of Weyl almost periodic functions and Weyl ergodic components in Lebesgue spaces with variable exponent Lp(x). We investigate the invariance of (asymptotical) Weyl almost periodicity with variable exponent under the actions of convolution products, providing also some illustrative applications to abstract fractional differential inclusions in Banach spaces. The introduced classes of generalized (asymptotically) Weyl almost periodic functions are new even in the case that the function p(x) has a constant value p≥1, provided that the functions ϕ(x) and F(l,t) under our consideration satisfy ϕ(x)≠x or F(l,t)≠l(−1)/p.
