Abstract
The aim of this article is to study the $L^p$-boundedness of pseudo-differential operators on a homogeneous tree $ \mathfrak X $. For $p\in (1,2)$, we establish a connection between the $L^{p}$-boundedness of the pseudo-differential operators on $ \mathfrak X $ and that on the group of integers $\mathbb Z$. We also prove an analogue of the Calderón–Vaillancourt theorem in the setting of homogeneous trees for $p\in (1,\infty )\setminus \{2\}$.
