Hello dear Wikipedia editors. The content of the article was partially taken from the website: http://www.math.tau.ac.il/~ybenja/

Where it explicitly says at the bottom of the page that:

Except where otherwise noted, content (text in pages, not files) on this site

is licensed under a Creative Commons Attribution 3.0 License.

Hence, the content can freely be added to Wikipedia.

I'd appreciate any help in improving this article.
