To avoid inconsistencies, the modern theory of Ramanujan summation requires that f is "regular" in the sense that the higher-order derivatives of f decay quickly enough for the remainder terms in the Euler—Maclaurin formula to tend to 0.

Ramanujan tacitly assumed this property. Instead, such a series must be interpreted by zeta function regularization.

For this reason, Hardy recommends "great caution" when applying the Ramanujan sums of known series to find the sums of related series.

Stable means that adding a term to the beginning of the series increases the sum by the same amount. This can be seen as follows. By linearity, one may subtract the second equation from the first subtracting each component of the second line from the first line in columns to give.

For example, if zeroes are inserted into arbitrary positions of a divergent series, it is possible to arrive at results that are not self-consistent, let alone consistent with other methods.

For an extreme example, appending a single zero to the front of the series can lead to inconsistent results. One way to remedy this situation, and to constrain the places where zeroes may be inserted, is to keep track of each term in the series by attaching a dependence on some function.

The implementation of this strategy is called zeta function regularization. The latter series is an example of a Dirichlet series.

The benefit of introducing the Riemann zeta function is that it can be defined for other values of s by analytic continuation.

The eta function is defined by an alternating Dirichlet series, so this method parallels the earlier heuristics. Where both Dirichlet series converge, one has the identities:.

Smoothing is a conceptual bridge between zeta function regularization, with its reliance on complex analysis , and Ramanujan summation, with its shortcut to the Euler—Maclaurin formula.

Instead, the method operates directly on conservative transformations of the series, using methods from real analysis. The cutoff function should have enough bounded derivatives to smooth out the wrinkles in the series, and it should decay to 0 faster than the series grows.

For convenience, one may require that f is smooth , bounded , and compactly supported. The constant term of the asymptotic expansion does not depend on f: Ramanujan wrote in his second letter to G.

Hardy , dated 27 February Ramanujan summation is a method to isolate the constant term in the Euler—Maclaurin formula for the partial sums of a series.

To avoid inconsistencies, the modern theory of Ramanujan summation requires that f is "regular" in the sense that the higher-order derivatives of f decay quickly enough for the remainder terms in the Euler—Maclaurin formula to tend to 0.

Please help improve this section by adding citations to reliable sources. Using sigma summation notation the sum of the first m terms of the series can be expressed as.

Nonetheless, in the midth century, Leonhard Euler wrote what he admitted to be a paradoxical equation:. A rigorous explanation of this equation would not arrive until much later.

For later reference, it will also be useful to see the divergence on a fundamental level. This derivation is depicted graphically on the right.

A generalized definition of the "sum" of a divergent series is called a summation method or summability method.

There are many different methods some of which are described below and it is desirable that they share certain properties with ordinary summation.

What the above manipulations actually prove is the following: The Cauchy product of two infinite series is defined even when both of them are divergent.

The partial sums are:. It has been proven that C, n summation and H, n summation always give the same results, but they have different historical backgrounds.

In a report, Leonhard Euler admits that the series diverges but prepares to sum it anyway:. But I have already noticed at a previous time, that it is necessary to give to the word sum a more extended meaning Euler proposed a generalization of the word "sum" several times.

One can take the Taylor expansion of the right-hand side, or apply the formal long division process for polynomials. Euler also seems to suggest differentiating the latter series term by term.

Euler applied another technique to the series: To compute the Euler transform, one begins with the sequence of positive terms that makes up the alternating series—in this case 1, 2, 3, 4, The first element of this sequence is labeled a 0.

Next one needs the sequence of forward differences among 1, 2, 3, 4, The Euler transform also depends on differences of differences, and higher iterations , but all the forward differences among 1, 1, 1, 1, The Euler summability implies another kind of summability as well.

The general statement can be proved by pairing up the terms in the series over m and converting the expression into a Riemann integral.

For positive integers n , these series have the following Abel sums: For even n , this reduces to. This last sum became an object of particular ridicule by Niels Henrik Abel in Divergent series are on the whole devil's work, and it is a shame that one dares to found any proof on them.

One can get out of them what one wants if one uses them, and it is they which have made so much unhappiness and so many paradoxes.

Can one think of anything more appalling than to say that. Here's something to laugh at, friends. The series are also studied for non-integer values of n ; these make up the Dirichlet eta function.
