Abstract

Assuming Jensen's diamond principle (\diamondsuit) we construct for every natural number n>0n>0 a compact Hausdorff space KK such that whenever the Banach spaces C(K)C(K) and C(L)C(L) are isomorphic for some compact Hausdorff LL, then the covering dimension of LL is equal to nn. The constructed space KK is separable and connected, and the Banach space C(K)C(K) has few operators i.e. every bounded linear operator T:C(K)C(K)T:C(K)\rightarrow C(K) is of the form T(f)=fg+S(f)T(f)=fg+S(f), where gC(K)g\in C(K) and SS is weakly compact.
