Expansion and rewrite[edit]

Since Manjul Bhargava won the Fields medal, and this is one of more easily understood results, I've rewritten this page to make it clearer to nonexperts, and added more references.

The page mentioned "integer valued integral quadratic forms". How are they different from integral quadratic forms? I think not at all... so I've changed this as part of my rewrite.

The rewrite generally looks good to me. But the claim "For example, x2 + xy + y2 is integral but does not have integral matrix." is not true - it does have an integral matrix "(1 1 // 0 1)", since the article does not require the matrix to be symmetric. I suppose the "symmetric" condition should be added? --Roentgenium111 (talk) 10:31, 14 August 2014 (UTC)
