Pointwise multipliers for Triebel--Lizorkin and Besov spaces on Lie groups

Tommaso Bruno, Marco M. Peloso, Maria Vallarino

On a general Lie group $G$ endowed with a sub-Riemannian structure and of local dimension $d$, we characterize the pointwise multipliers of Triebel--Lizorkin spaces $F_{\alpha }^{p,q}$ for…
