p. 89 - 103 The Cesàro χ2 sequence spaces defined by a modulus N. Subramanian Received: July 30, 2011; Accepted: December 7, 2011 Abstract. In this paper we defined the Cesàro χ2 sequence space Cespq(χ2f) defined by a modulus and exhibit some general properties of the space. Keywords: Gai sequence; analytic sequence; modulus function; double sequences; Cesàro.
