We introduce a concept of convergence of order , with 0< 1, with respect to a summability matrix method A for sequences (which generalizes the notion of statistical convergence of order ), taking values in (')-groups. Some main properties and di erences with the classical A-convergence are investi- gated. A Cauchy-type criterion and a closedness result for the space of convergent sequences according our notion is proved.
