Double Sequence And Series. We use the sigma notation that is, the greek symbol “σ” for the series which means “sum up”. Sequence and series is one of the basic topics in arithmetic.

An arithmetic progression is one of the common examples of sequence and series. To achieve this, the definitions given by lubkin (8) and gray and atchison (2,9) are first extended Then the series of this sequence is 1 + 4 + 7 + 10 +… notation of series.

Rates of convergence of double series 2.1 theory this theory is concerned with defining and investi gating a transformation which will accelerate the convergence of the double sequence of partial sums of a double series. Then there exists a n ǫ > 0 such that for any δ > 0 there e x ist ( x, y ) , ( ¯ x, ¯ y ) ∈ i × i with For instance, the series 1+2+3….

+ an is abbreviated as 1 n k k a = To each double sequence s: Series are often represented in compact form, called sigma notation, using the greek letter ∑ (sigma) as means of indicating the summation involved.
This Book Exclusively Deals With The Study Of Almost Convergence And Statistical Convergence Of Double Sequences.
Lim m;n!1 a m;n = ameans that for every >0 there is an integer kso that if m kand n kthen ja m;n aj. Let b m = lim n!1 a m;n. A sequence is a function from a subset of the set of integers (typically the set {0,1,2,.} or the set {1,2,3,.} to a set s.
To Each Double Sequence X :
Thus convergent double series may be divided into two classes according A double series whose terms are functions displays many properties of ordinary series of functions and many concepts are common to. Then the series of this sequence is 1 + 4 + 7 + 10 +… notation of series.
N×N −→ C, There Corresponds Three Important Limits;
We call an a term of the sequence. Suppose fa m;ngis a double sequence. An arithmetic progression is one of the common examples of sequence and series.
