  Abstract:
Let CF(X) denote the socle of C(X). It is shown that X is a P-space if and only if C(X) is ℵ0-selfinjective ring or equivalently, if and only if [(C(X))/(CF(X))] is ℵ0-selfinjective. We also prove that X is an extremally disconnected P-space with only a finite number of isolated points if and only if [(C(X))/(CF(X))] is selfinjective. Consequently, if X is a P-space, then X is either an extremally disconnected space with at most a countable number of isolated points or both C(X) and [(C(X))/(CF(X))] have uncountable Goldie-dimensions. Prime ideals of [(C(X))/(CF(X))] are also studied.
