About calculating a Green's function @Ron Gordon I have added a sub part to the question. |

About calculating a Green's function @Ron Gordon Great! Hope to see your explanations for this question. (..Also you can see another Green's function question that I have asked - with coupled differential equations...) |

About calculating a Green's function @Ron Gordon x goes between 0 and 1 - but this is a physics detail - does it mathematically matter? |

How can the general Green's function of a linear homogeneous differential equation be derived? @RonGordon I guess the point is that $\lambda$ makes sense only when the differential operator is sourced - then arbitrary Lambda are allowed and then the source propagated with this $G_\lamda$. If the source is 0 then only $\lambda$ that makes sense are the $\lambda_n$ - the eigenvalues of the operator. So one never has the $\lambda = \lambda_n$ singularity since one never uses this Green's function in the absence of a source - which will allow lambda to be chosen arbitrarily. |

How can the general Green's function of a linear homogeneous differential equation be derived? @RonGordon So what are the $\lambda_n$ in that other question? (..aren't both the $\lambda _n$ also 1/4 for both the eigen functions and then here the denominator becomes 0..) And how will you get a split function from this formalism? In that other question how does $y(0)$ condition become the $G(x<x')$ condition and vice-versa for $y(\pi)$? I don't get this translation. |

How can the general Green's function of a linear homogeneous differential equation be derived? @Ron Gordon So what is $\lambda$ here? Who determines that? How does this method match with the method you said here - math.stackexchange.com/questions/284870/… |

A transcendental equation Why are you looking at the function "y= z tan z" ? I would think you should look at $y = (tan z)/z" (..if you want to intersect it with "-1/Sqrt(z_0^2 - z^2)"..) |

A transcendental equation @Kaster I haven't been very careful about "min" vs "inf". I would like to know what is the answer, however accurately it can be given. |

A (contour?) integration (even if by using Mathematica!) @DonAntonio I can see your observation, May be you can look through my questions and suggest if there is any answer which I should have accepted but I didn't. I see most of my questions being unanswered and only some of the answers that have come are really complete or very useful. If I have missed any then may be you can point out. |

Some manipulations on a Riemannian manifold Thanks for the help. You can see my comment above for a reference to these. Can you explain what you mean by ``exponential map of point $\phi$ in the diretion if $\xi$" - can you kindly elaborate on that? Like I would have thought that $e^\xi$ is already a point on the manifold then what is $e^{\xi}\phi$? - what is this implicit "multiplication" ? |
