The Rokhlin property for actions of\r\ninfinite infinite compact groups has also been studied. We define\r\nand investigate the tracial Rokhlin property for actions of second\r\ncountable compact groups on simple unital C*-algebras. The naive\r\ngeneralization of the verrsion for finite groups does not appear to\r\nbe good enough. We have a property which, first, allows one to prove\r\nthe expected theorems, second, is \"almost\" implied by the version\r\nfor finite groups when the group is finite, and, third, admits\r\nexamples.\r\n\r\nThis is joint work with Javad Mohammadkarimi.\r\n","speaker_web":null,"announcement":null,"descfiles_signed_ids":"[]","online":false,"slug":"2022-06-06","shift":{"beginning":{"hour":11,"minute":0,"second":0,"second_of_day":39600},"ending":{"hour":12,"minute":0,"second":0,"second_of_day":43200},"exclude_end":false,"range":"[39600,43200]"},"announcement_i18n":{"en":"","he":""},"duration":"[2022-06-06 08:00:00 UTC,2022-06-06 09:00:00 UTC]","id":894,"created_at":"2022-05-31T09:43:44.720+03:00","updated_at":"2022-05-31T09:43:44.720+03:00","admin_users":[],"summary":"N.
