Not suitable for this site | |
| S Feb 19, 2016 at 0:57 | comment | added | m_goldberg | I'm voting to close this question as off-topic because the issue it raises is not a Mathematica issue but a mathematical one. That it is formulated in terms of Mathematica is not sufficient to make it an appropriate question for Mathematica.SE. | |

Minor clean-up
|
| Feb 18, 2016 at 9:21 | comment | added | rhermans | Will this ultimately become a Mathematica question? Shouldn't the OP include Mathematica code defining the relevant functions and of the attempts so far? Some focus on the programmatic tools that allow the integral to be resolved? This is already been nominated to close on ground of "unclear what you're asking". | |

| Mar 1, 2014 at 1:54 | comment | added | zakk | @george2079: it should converge, at least it is eq. 5 in this paper: journals.aps.org/prl/pdf/10.1103/PhysRevLett.74.1633 The authors refer to an unpublished paper for the numerical part, commenting as follows: letting $x=\tan(\beta)$, we set up a Gaussian-quadrature grid for $\beta$ and convert the above equations into a matrix form which can be solved iteratively. The logarithmic singularities are treated separately. | |

| Feb 28, 2014 at 19:53 | comment | added | george2079 | At a glance I'm having a hard time seeing how that integral could possibly converge for a<x<b. Assuming i'm wrong and it does converge your challenge is to develop a quadrature rule that is accurate at the singular point. Have fun..! (I think this really is a math.stackexchange question in any case) (BTW The right most "=1" is a typo right..?) | |
