On the ideal convergence of subsequences and rearrangements of a real sequence
The authors examine the ideal convergence of subsequences and rearrangements of a real sequence. They obtain a necessary and sufficient condition for a sequence to be statistically convergent. In the last section they present some results related to the \(I_{\varphi}\)-continuity, the set of \(I_{\varphi}\)-limit points and set of \(I_{\varphi}\)-cluster points.
