How can I find if two isometries are conjugate of each other or not? @CameronBuie - I tried to compose the isometries using the equation you gave and got $ {az + 28bz + b \over cz+28dz+d} = {5az + 5b + 19cz + 19d \over az+b+4cz+4d}$, but then it just got fairly messed up from there. |

How can I find if two isometries are conjugate of each other or not? @GerryMyerson - Apologies, I wasn't readily near a terminal this weekend. But yes, I'm not sure what exactly is meant by "conjugate" isometries, hence the lost comment. I will try to improve the wording on future questions. |

How can I find if two isometries are conjugate of each other or not? @CameronBuie - Could you elaborate on what FLT is ? All I could find on google about it is Fermat's Last Theorem, but this is not related to that. |

Finding a hyperbolic isometry that fixes the point $x = 2$ and $x = 17$ Awesome I appreciate all your help. I have another question on a related note and didn't want to open another topic since it is so related. If I had a parabolic isometry that fixes $x = 17$, I assume the first step would be same $f(z) = z$ and $ a + d = 2$? But since the equation has two roots, but I have only one fixed points, how should I proceed in that case ? |

Finding a hyperbolic isometry that fixes the point $x = 2$ and $x = 17$ Checking for hyperbolic isometry, isn't that just checking $a+d > 2$ and $ad-bc \ne 0$, or is there something more involved than that ? |

Finding a hyperbolic isometry that fixes the point $x = 2$ and $x = 17$ So when you say to check whether the resulting function $f$ does what it is supposed to do, does that mean put the values of a,b,c,d in the original equation and make sure that they equal to 2 or 17 ? |

Finding a hyperbolic isometry that fixes the point $x = 2$ and $x = 17$ I'm trying to understand the process so please bear with me. At first I see that you set f(z) = z. I'm not sure why, could you please explain this? In the end, to get the answer should I just choose any a, b, c, d values that satisfy all those equations ? |

Calculating hyperbolic distance between two points @J.M. - I don't have the tab open anymore, but it was in one of the links I found through googling |

Find an orientation preserving isometry $f (z) = \frac{az+b}{cz+d}$ such that $f (i) = 17 + 3i$ Thank you! I'd like to read more about polynomials over z preserving orientation and holomorphic functions because I don't understand those yet. Any specific sources you suggest ? |
