Abstract: In this paper we study spaces of nuclear operators $ {\mathcal N}(C(Q))$ and spaces of compact operators $ {\mathcal K}(C(Q))$ on spaces of continuous functions $ C(Q),$ where $ Q$ is a countable compact metric space, in connection with the C. Bessaga and A. Pełczyński isomorphic classification of these spaces.

We show that the spaces $ {\mathcal K}(C(Q))$ [resp. $ {\mathcal N}(C(Q))$] and $ {\mathcal K}(C(Q'))$ [resp. $ {\mathcal N}(C(Q'))$] are isomorphic if, and only if, $ C(Q)$ and $ C(Q')$ are isomorphic. We show also that $ {\mathcal N}(C(Q))$ is not isomorphic to a subspace of $ {\mathcal K}(C(Q)).$
