Complexity of matrix inversion and solving Ax = b

edit

Thanks for your edits at Computational complexity of mathematical operations. They suggest that you might be able to help me out. The article currently says that the complexity of matrix inversion via Gaussian elimination is cubic. Is there a faster algorithm known? More important in applications is of course the complexity of solving Ax = b where A is a matrix. I seem to remember having read somewhere that there are also fast algorithms (i.e., faster than cubic) for this. Would you be able to add something on this subject to the article, or just give me some references? Don't worry about it if it costs too much time. -- Jitse Niesen (talk) 01:21, 31 January 2007 (UTC)Reply

Context

edit

Please don't start a Wikipedia article by saying "In a Lorentzian manifold,..." without first telling the reader that mathematical physics (or whatever context description you prefer to that) is what it's about. You can't assume the lay reader has heard of Lorentzian manifolds, but of course the lay reader has heard of mathematical physics. Michael Hardy (talk) 02:16, 3 August 2010 (UTC)Reply

Proposed deletion of Steve Carlip

edit
 

The article Steve Carlip has been proposed for deletion because under Wikipedia policy, all biographies of living persons created after March 18, 2010, must have at least one source that directly supports material in the article.

If you created the article, please don't take offense. Instead, consider improving the article. For help on inserting references, see Wikipedia:Referencing for beginners or ask at Wikipedia:Help desk. Once you have provided at least one reliable source, you may remove the {{prod blp}} tag. Please do not remove the tag unless the article is sourced. If you cannot provide such a source within ten days, the article may be deleted, but you can request that it be undeleted when you are ready to add one.

Editing other user's "User:" page

edit

[1]

You edited other user's "User:" page, but it is the personal talk page ("User talk:" namespace) where to ask questions. Link to appropriate talk page is present in a tab above the page, or in the navigation bar at left side of a wiki page, depending on a skin. Go to it and make a new thread. Defacing "User:" pages in a such way is not admissible. Incnis Mrsi (talk) 15:51, 8 March 2011 (UTC)Reply

Proposed deletion of Vdwnumbers.org

edit
 

The article Vdwnumbers.org has been proposed for deletion because of the following concern:

I find no evidence that this project has achieved notability. Scant coverage found for vdwnumbers or "Van der waerden" boinc or "van der waerden" "Berkeley Open Infrastructure".

While all constructive contributions to Wikipedia are appreciated, content or articles may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the article to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion. —Largo Plazo (talk) 03:48, 8 September 2015 (UTC)Reply
