| All that is left now is the case where ρ is irreducible. I'm sure there is a better way [...] but I have to get the kids up for school. Suddenly I am under time pressure. |

| 'heuristic' does not mean 'not precise'! I know it's often used that way but that's not what it means. |

| Serge Lang's Algebra was my first serious encounter with mathematics, the event was a very singular defining moment in my life. Back then, I was firmly intent on becoming a poet... |

| Like many people (but not all people), I have trouble thinking in terms of formulas such as that for the Schwarzian. For me, a geometric image works much better. |

| In this case the printed name Erdös is an approximation of the correct typography and you should use the correct version Erdős if possible. |

| You want G conn'd reductive. Let R be henselian (e.g., complete) dvr with frac. field K, and G and G′ smooth affine R-groups with conn'd reductive fibers. [...] |
