Mathematical Communications. 6(2001), 165-172.https://hdl.handle.net/11486/264In this paper we extend concepts of statistical limit superior and inferior (as introduced by Fridy and Orhan) to I?limit superior and inferior and give some I?analogue of properties of statistical limit superior and inferior for a sequence of real numbers. Also we extend the concept of the statistical core to I?core for a complex number sequence and get necessary conditions for a summability matrix A to yield I?core {Ax} ? I?core {x} whenever x is a bounded complex number sequence.enStatistical limit superior and inferiorStatistical core of a sequenceI?convergent sequenceArticle
