Obvious examples are when X is itself the product of two graphs but there are many other examples. I will give a quick survey of complete squa re complexes with an aim towards describing some problems about them and d escribing some small examples that are 'irreducible' in the sense that the y do not have a finite cover that is a product.\n\nhttps://mcgill.zoom.us/ j/98910726246?pwd=VHlzTzdTZGtqcHVuWGNKdys4d0FzQT09\n\nZoom ID: 989 1072 62 46\n Password: delta\n DTSTART:20210224T200000Z DTEND:20210224T210000Z SUMMARY:Daniel Wise (ɬÀï·¬) URL:/mathstat/channels/event/daniel-wise-mcgill-univer sity-329060 END:VEVENT END:VCALENDAR
