Wikipedia:Picture peer review/Functorial Resolution of Singularities

From Wikipedia, the free encyclopedia
Original - Functorial Resolution of Singularities. Observe that the resolution does not stop after the first blowing-up, when the strict transform is smooth, but when it is simple normal crossings with the exceptional divisors.

Resolution of singularities is a complicated process both computationally and theoretically. In some simple cases it has not too many steps and it can be shown explicitly without. In the given example the basic important features of the resolution are shown. The diagram is simple as the topic requires to avoid distractions. The blowings-up and the exceptional divisors are given. The article Resolution_of_singularities didn't have any information about how the resolution is produced. The present image is a first step in a plan to add a sketch of the proof in the article. There are some issues I don't like from the image. Firstly I think it would be good to have some margin, at least a little and secondly the current version is a PDF, when I made the SVG the text lost the spacing. I don't know so far how to solve these. Posting the image here is also a way of catching attention by editors proficient in vector graphics. Is possible but I didn't know about some other page/project dedicated to retouching images.

  • When I click on the image, I get the error message

  • I have the get the same error. Right clicking and saving target give you the file. That's another problem that needs to be solved. Franklin.vp  17:33, 2 November 2009 (UTC)[reply]
  • It seems a bit blurry, is this svg safe or regular fonts? Nezzadar [SPEAK] 17:52, 2 November 2009 (UTC)[reply]
  • I guess it is something about the way wikipedia displays PDFs, when you save the file the SVG is there with its infinite resolution. Thats why the SVG has to be produced. When I did it with Inkscape (as ZooFari suggested me) the text lost the spaces (see first version of the file). That's why I uploaded the PDF so that at least the article has the information readable until the technical corrections of the file are done.  Franklin.vp  17:59, 2 November 2009 (UTC)[reply]
  • Ah, I see. I also flirted with inkscape, but got rid of it since I don't have the time to learn it. I use Paint.NET, a freeware that mimics Adobe Photoshop, but does not make svgs. Durova uses GIMP, another freeware, or at least I think she uses that. Someone suggested it to me anyhow. Try those. Nezzadar [SPEAK] 18:31, 2 November 2009 (UTC)[reply]

  • Requesting withdrawal Thanks to ZooFari the visual tweaks needed were done. He said maybe some XML cleaning was needed but I do not know about that. Externally it looks as I ( or the article) needed. Franklin.vp  23:53, 2 November 2009 (UTC)[reply]
