The 9 pages that link to Alternating harmonic series, each with the reason it gives.

• Conditional convergenceBroader topic: It converges conditionally, providing the standard concrete example.

• Alternating series testBroader topic: Its decreasing terms tend to zero, so it is a standard direct application of the test.

• Cauchy productRelated: Its conditional convergence illustrates why Cauchy-product identities need hypotheses.

• Abel's theorem (power series)Broader topic: Its power series gives a classic limit argument for evaluating the endpoint sum.

• Summability methodCompared with: It shows that alternating terms can yield an ordinary sum without generalized summation.

• Riemann series theoremBroader topic: It is the standard example whose rearrangements illustrate the theorem.

• Abel's testBroader topic: Its sign factor has bounded partial sums, while the reciprocal factor decreases to zero.

• Cauchy's convergence testBroader topic: Its tails can be bounded directly, establishing convergence without absolute convergence.

• Nth-term testBroader topic: Its vanishing terms pass the test, while the alternating series test establishes convergence.
