Cp(X) denotes the space of continuous real-valued functions on a Tychonoff space X with the topology of pointwise convergence. A locally convex space (lcs) E with the weak topology is denoted by Ew. First, we show that there is no a sequentially continuous linear surjection T: Cp(X) → Ew, if E is a lcs with a fundamental sequence of bounded sets. Second, we prove that if there exists a sequentially continuous linear map from Cp(X) onto Ew for some infinite-dimensional metrizable lcs E, then the completion of E is isomorphic to the countable power of the real line Rω. Illustrating examples are provided.
