    For a topological space $X$ we denote by $CL(X)$ the collection of all non-empty closed subsets of $X$. Suppose we have a map $J$ which assigns in some coherent way to every topological space $X$ some topology $J \ (X)$ on $CL(X)$. In this paper we study continuity and inverse continuity of the map $i_{A,X}:(CL(A),J(A))\rightarrow \(CL(X),J(X))$ defined by $i_{A,X}(F)=\bar F\ $ whenever $F \in \ CL(A)$ for various assignment $J$; in particular, for locally finite topology, upper Kuratowski topology, or Attouch-Wets topology, etc.
