Abstract:
A spaceX is star-LindelÊ f if for every open cover U ofX, there ex ists a coun tab le subsetF o fX such that St (F, U) =X. In th is note, we d iscuss the re la tionsh ip be tw een star-L inde lÊ f spaces and re lated spaces, and g ive an examp le show ing the product o f tw o countab le compact spaces is not star-L inde lÊ .f
