Abstract
In the present paper, an attempt has been made to investigate the cardinal functions corresponding to certain concepts associated with the Katetov H-closed extension of an infinite discrete space. The concepts of density, spread, cellularity, weight and tightness of a topological space, as given by JUHASZ [4], are recalled here for their determination in respect of the said Katetov extension of an infinite discrete space.
