Alas, for some parameters the continued fraction R_η does not converge; moreover, there are converging instances where the AGM relation itself does not hold. To unravel these dilemmas we herein establish convergence theorems, the central result being that R₁ converges whenever |a| ≠|b|. Such analysis leads naturally to the conjecture that divergence occurs whenever a = be^iϕ with cos^2ϕ ≠ 1 (which conjecture has been proven in a separate work) [Borwein et al. 04b.] We further conjecture that for a/b lying in a certain—and rather picturesque—complex domain, we have both convergence and the truth of the AGM relation.]]> Sat 24 Mar 2018 08:15:36 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:10335 Sat 24 Mar 2018 08:07:00 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:6480 Sat 24 Mar 2018 07:47:13 AEDT ]]>
