The text that you have inserted in ellipsoid is also a copyright violation of the same article (it does not matter that you are the author, as soon as it is published, the copyright is transferred to the editor).

Moreover, even if your addition to the article ellipsoid were not a copyright violation, it could not be accepted in Wikipedia, as being an original research, that lacks of reliable secondary sources. Also, being the author of the paper, your edit is a conflict of interest. D.Lazard (talk) 11:30, 16 March 2018 (UTC)

You currently appear to be engaged in an edit war&#32; according to the reverts you have made on Ellipsoid. Users are expected to collaborate with others, to avoid editing disruptively, and to try to reach a consensus rather than repeatedly undoing other users' edits once it is known that there is a disagreement. Please be particularly aware that Wikipedia's policy on edit warring states: If you find yourself in an editing dispute, use the article's talk page to discuss controversial changes; work towards a version that represents consensus among editors. You can post a request for help at an appropriate noticeboard or seek dispute resolution. In some cases it may be appropriate to request temporary page protection. If you engage in an edit war, you may be blocked from editing.—Anita5192 (talk) 05:53, 17 March 2018 (UTC)
 * 1) Edit warring is disruptive regardless of how many reverts you have made.
 * 2) Do not edit war even if you believe you are right.

You can also be blocked for sockpuppetry for the use of 129.108.148.21 (talk), which is the use of multiple accounts to deceive, mislead, or evade other editors.—Anita5192 (talk) 05:53, 17 March 2018 (UTC)
