Abstract: Let E be an infinite-dimensional linear subspace of $ C(S)$, the space of bounded continuous functions on a locally compact Hausdorff space S. If $ \mu $ is a regular Borel measure on S, then each element of E may be regarded as a multiplication operator on $ {L^p}(\mu )(1 \leqq p < \infty )$. Our main result is that the strong operator topology this identification induces on E is properly weaker than the strict topology. For E the space of bounded analytic functions on a plane region G, and $ \mu $ Lebesgue measure on G, this answers negatively a question raised by Rubel and Shields in [9]. In addition, our methods provide information about the absolutely p-summing properties of the strict topology on subspaces of $ C(S)$, and the bounded weak star topology on conjugate Banach spaces.
