Let f be a mapping (i.e., continuous transformation) of a topological space X onto a topological space Y. It is of interest to investigate the properties of X which are inherited by Y under the mapping f. In particular, if f is a homeomorphism, X and Y are topologically equivalent, so that Y will share all the topological properties of X. Hovever, under 1ess restricted oonditions on f , many of the properties such as connectedness, compactness, separability, local separability (i.e., first countability) and strong separability (i.e., second countability), etc., will be inherited by Y. In this work, we are interested in investigating some important classes of mappings: open mappings, closed mappings and perfect mappings, and in determining how the image space is affected under such mappings. These mappings play fundamental role in many studies, e.g., the theory of function of one or several complex variables. Work along these lines have been initiated by G. T. Whyburn, S. Stoilow, H. Grauert, B. Remmert and K. Stein.
