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