A compact Hausdorff space is called Eberlein compact (EC) if it is homeomorphic to a weakly compact subset of a Banach space. A topological space (X,\(\tau)\) is called fragmented by a metric \(\rho\) defined on X if for each nonempty subset \(A\subset X\) and for each \(\epsilon >0\) there exists a \(\tau\)-open subset U of X such that \(A\cap U\neq ...

The author shows that the space \(X^{[0,1]}\) of continuous maps \([0,1]\to X\) with the compact-open topology is not locally compact for any space \(X\) having a nonconstant path of closed points. For a \(T_1\)-space, it follows that \(X^{[0,1]}\) is locally compact if and only if \(X\) is locally compact and totally path disconnected, where \(X\) is ...
