Abstract
Given an ideal on the positive integers, a real sequence is said to be -statistically convergent to provided that for all neighborhoods of and all . First, we show that -statistical convergence coincides with -convergence, for some unique ideal . In addition, is Borel [analytic, coanalytic, respectively] whenever is Borel [analytic, coanalytic, resp.]. Then we prove, among others, that if is the summable ideal or the density zero ideal then -statistical convergence coincides with statistical convergence. This can be seen as a Tauberian theorem which extends a classical theorem of Fridy. Lastly, we show that this is never the case if is maximal.
