A NOTE ON THE WC-MAPPINGS
Ivan Lončar
Sažetak
Let X be a topological T| space. By wX we denote the Wallman compactifi cation of X. A mapping f : X—•¥ is a wc-mapping if f has an unique closed extension wf ; wX—»-wY.
The main purpose of this paper is to give some external and internal characterizations of the wc-mappings. The main theorem establishes that if Y is a Hausdorff Frechet space then f is a wc-mapping iff f is an uw-mapping (Theorem 1T3.)
