عنوان	CONTRACTABILITY OF ULTRAPOWERS OF BANACH ALGEBRAS
نوع پژوهش	مقاله ارائه شده کنفرانسی
کلیدواژه‌ها	Banach algebra, ultrafilter, ultrapowre, amenability, ultra-amenability, contractability and ultra-contractability
چکیده	We study when contractability of Banach algebras are stable under the ultrapower consructions. We extend some general results of contractability of Banach algebras to ultrapowers of them. We investigate the relationship between ultra-contractability with both of contractability and ultra-amenability.
