Let X be a completely regular Hausdorff space and E a real normed space. We examine the general properties of locally solid topologies on the space C b ( X , E ) of all E -valued continuous and bounded functions from X into E . The mutual relationship between locally solid topologies on C b ( X , E ) and C b ( X ) ( = C b ( X , ) ) is considered. In particular, the mutual relationship between strict topologies on C b ( X ) and C b ( X , E ) is established. It is shown that the strict topology β σ ( X , E ) (respectively β τ ( X , E ) ) is the finest σ -Dini topology (respectively Dini topology) on C b ( X , E ) . A characterization of σ -Dini and Dini topologies on C b ( X , E ) in terms of their topological duals is given.

We examine the general properties of locally solid topologies on the space $C_b(X,E)$ of all $E$-valued continuous and bounded functions from $X$ into $E$. The mutual relationship between locally solid topologies on $C_b(X,E)$ and $C_b(X)$$(=C_b(X,\mathbb {R}))$ is considered. In particular, the mutual relationship between strict topologies on $C_b(X)$ and $C_b(X,E)$ is established. It is shown that the strict topology $\beta _\sigma (X,E)$ (respectively $\beta _\tau (X,E)$) is the finest $\sigma $-Dini topology (respectively Dini topology) on $C_b(X,E)$. A characterization of $\sigma $-Dini and Dini topologies on $C_b(X,E)$ in terms of their topological duals is given.
