Abstract

\(C_p(X)\) 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 \(E_{w}\). First, we show that there is no a sequentially continuous linear surjection \(T: C_p(X)\rightarrow E_w\), 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 \(C_p(X)\) onto \(E_w\) for some infinite-dimensional metrizable lcs E, then the completion of E is isomorphic to the countable power of the real line \({\mathbb {R}}^{\omega }\). Illustrating examples are provided.
