| Mar 3, 2011 at 14:25 | comment | added | Steven Gubkin | @Victor - I think the point is that some people who come to MO just to answer questions might see the dark green box next to this one and pass it by without a glance. I myself do not treat MO this way, but I guess some people might. For attracting such people the [Still Open] is needed. | |

| Aug 5, 2010 at 19:23 | comment | added | Victor Protsak | I think that you've already explained it well in the opening paragraph (in bold, so hard to miss). If a person has something to contribute (and doesn't care about MO formalities), experience suggests that (s)he would do it no matter what. For the others, it's a visual annoyance and may be interpreted as an unfair way to attract attention. | |
| Aug 5, 2010 at 18:49 | comment | added | Ilya Grigoriev | @Victor: What do you mean it's not accurate? The reason I put it there is that I don't want people to think that this question is answered even though it has an accepted answer, is colored accordingly in lists, etc. How else should I communicate this information? | |
| Aug 5, 2010 at 2:22 | comment | added | Victor Protsak | I agree that it's an interesting question, but as a courtesy to fellow MOers, can you, please, remove [STILL OPEN] from the title? This is visual spam and not particularly accurate, as you explain in the opening paragraph. | |

| Jul 27, 2010 at 21:51 | comment | added | Victor Protsak | I taught Gauss-Bonnet theorem in one class following the book of Rashevskii (in Russian; you can find a copy on the I-net). His geometric explanation using parallel transport is very good, but maybe it's more than one can reasonably hope to impart in a 5-day course. By GB I mean the version with a closed piecewise-smooth contour, $$\iint Kd\sigma +\int \kappa_g ds +\sum\Delta \psi = 2\pi.$$ | |

| Jul 27, 2010 at 13:46 | comment | added | Andrey Rekalo | Marcel Berger gives an illuminating presentation of the Theorema Egregium and discusses the connection of the Gauss-Bonnet formula with parallel transport in ["A panoramic view of Riemannian geometry"][1]. [1]: books.google.co.uk/… | |
