Double dot product[edit]

In the definition of the double dot product I believe (ab):(xy) = (b.x)(a.y) source: Deen, William M. "Analysis of Transport Phenomena." Oxford University Press: New York, 1998. ISBN: 978-0-19-508494-8

I would change this but I don't have the software to render the expression neatly. 18.252.6.200 (talk) 00:37, 14 September 2009 (UTC)

You are correct. I will change this, as well as most of the notation on this page. As it stands, it's extremely ugly and non-standard.129.128.221.64 (talk) 18:08, 25 November 2009 (UTC)

Whew! That was enough work for me for now. I'm getting the two references mentioned here from my local library and I'll fix the notation on everything else, as well as check for correctness. This article -will- be the article people use to understand Dyads. 129.128.221.64 (talk) 18:50, 25 November 2009 (UTC)
Upon further research it seems that there are two different conventions in defining the double dot product. I'll put it in the article. 129.128.221.64 (talk) 23:19, 1 December 2009 (UTC)
Done with my edits. Hopefully this article looks a lot cleaner and makes a little more sense. I think we should probably merge the other two dyad articles with this one. 129.128.221.64 (talk) 23:30, 1 December 2009 (UTC)
Done (now in 2012?...). Maschen (talk) 23:45, 23 August 2012 (UTC)

Applications?[edit]

This math is new to me. I was just wondering if there were any applications. It would be a helpful section to include. JKeck (talk) 17:46, 21 September 2011 (UTC)

standard basis dyads[edit]

Aren't the standard basis dyads at the bottom of the 3D Euclidean section transposed? — Preceding unsigned comment added by 173.25.54.191 (talk) 20:35, 9 September 2012 (UTC)

Well spotted. Fixed. — Quondum 06:51, 10 September 2012 (UTC)

Inner product[edit]

The Identities section claims that the dyadic product is "compatible with inner product," but the identity given is the definition of the dot product given in the Dyadic algebra section. I'm removing the "identity" on the assumpion that it's actually a definition; if this is wrong, please let me know. Vectornaut (talk) 19:21, 18 November 2013 (UTC)
