Abstract:
We provide non-smooth atomic characterizations for 2-microlocal Besov and Triebel–Lizorkin spaces with variable integrability$B^{w}_{p(\cdot),q(\cdot)}(\mathbb{R}^n)$ and $B^{w}_{p(\cdot),q(\cdot)}(\mathbb{R}^n)$. These spaces cover the classical Besov and Triebel–Lizorkin spaces as well as spaces of variable smoothness and integrability. As an application, we state a pointwise multipliers result for these spaces.
