Let E be a complex Banach space with open unit ball BE. The structure of the space of composition operators on the Banach algebra H(BE), of bounded analytic functions on BE with the uniform topology, is studied. We prove that the composition operators arising from mappings whose range lies strictly inside BE form a path connected component. When E is a Hilbert space or a C0(X)-space, the path connected components are shown to be the open balls of radius 2.
