Homomorphisms of the lattice of slowly oscillating functions on the half-line

Abstract

We study the space $H(\SO)$ of all homomorphisms of the vector lattice of all slowly oscillating functions on the half-line $\HH=[0,\infty)$. In contrast to the case of homomorphisms of uniformly continuous functions, it is shown that a homomorphism in $H(\SO)$ which maps the unit to zero must be zero-homomorphism. Consequently, we show that the space $H(\SO)$ without zero-homomorphism is homeomorphic to $\HH\times (0, \infty)$. By describing a neighborhood base of zero-homomorphism, we show that $H(\SO)$ is homeomorphic to the space $\HH\times (0, \infty)$ with one point added.
