Ramanujan wrote in his second letter to G. Convergent series Divergent series Conditional convergence Absolute convergence Uniform convergence Alternating series Telescoping series.

Stable means that adding a term to the beginning of the series increases the sum by the same amount. Ultimately it is this fact, combined with the Goddard—Thorn theorem , which leads to bosonic string theory failing to be consistent in dimensions other than The eta function is defined by an alternating Dirichlet series, so this method parallels the earlier heuristics.

The n th partial sum is given by a simple formula:. Because the sequence of partial sums fails to converge to a finite limit , the series does not have a sum.

One can take the Taylor expansion of the right-hand side, or apply the formal long division process for polynomials. One can take the Taylor expansion of the right-hand side, or apply the formal long division process for polynomials. Tucciarone, John January Divergent series Arithmetic series. Tucciarone, 1 2 3 4.

The spatial symmetry of the problem is responsible for canceling the quadratic term of the expansion.

Convergent series Divergent series Conditional convergence Absolute convergence Uniform convergence Alternating series Telescoping 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.

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

For an extreme example, appending a single zero to the front of the series can lead to inconsistent results.

John Baez even suggests a category-theoretic method 1 2 3 4 multiply pointed sets and the quantum harmonic oscillator. Euler also seems to suggest differentiating the latter series term by term. Euler also seems to suggest differentiating the latter series term by term. From Pythagoras to Riemannp. Stable means that adding a term to the beginning of the series increases the sum by the same amount!
