Abstract
In this paper, we study properties of the topological space of composition operators acting on the space \({\mathcal{H}^{\infty}}\) of Dirichlet series. Especially, we show that there are two compact composition operators which are not in the same path component on \({\mathcal{H}^{\infty}}\). This is in sharp contrast with the classical case where all compact composition operators on \({H^{\infty}}\) of one variable or several variables lie in the same path component.
