Let A=(a"n"k)"n","k"="1^~ be an infinite matrix and x=(x"k)"k"="1^~ a sequence of real or complex numbers. Then the A-transform of x is a sequence Ax=(A"n(x)) where A"n(x)[email protected]?"k"="1^~a"n"kx"k provided that the series converges for each n; and the sequence x is said to be A-summable if Ax is convergent. In this paper we define statistical A-summability of x, that is, x is said to be statistically A-summable if Ax is statistically convergent. We study here many other related concepts and provide some interesting examples. |
