摘要:
AbstractIn this paper we show: AC*‐algebraAwith identityeisC*‐nuclear (i.e. “nuclear” in the sense of LANCE[3, p. 159] or “propertyT” in the sense of TAKESAKI[6] if and only if the identity operator idAonAcan be approximated in the strong operator topology by completely positive linear operatorsVfromAintoAof finite rank with norm one andV(e)=e. From which follows that everyC*‐nuclearC*‐algebra (possible without identity) possesses the CPAP of LANCE[3, def. 3.5.]. This answers questions of LANCE[3, p. 173] and
