Untitled[edit]

Whoever put this in:

"In other words, if we hold the first entry the bilinear operator fixed, while letting the second entry vary, the result is a linear operator, and similarly if we hold the second entry fixed."

thankyou!

How about another example for a matrix B\in M_n(F) as a bi-linear form: B : F^nxF^n->F defined by v^TBw, v,w\in F^n

map vs operator[edit]

I think the term "operator" should be reserved for maps of a space into itself (or by extension ExE→E), while for the general case (in particular bilin.forms) the term "map" should be preferred. MFH: Talk 17:46, 27 May 2005 (UTC)

Agree. At any rate, we should keep our naming consistent; witness multilinear map vs. bilinear operator. -- Fropuff 18:03, 2005 May 27 (UTC)
Seems reasonable. I was wondering about the same topic some time ago. This should be put at Wikipedia:WikiProject Mathematics/Conventions.MathMartin 11:03, 29 May 2005 (UTC)
I've partially fixed this, but haven't gone so far as to move the page: I would, however, support such a move. Geometry guy 16:35, 13 May 2007 (UTC)
Yes, I agree. Someone with operator privs should perform the move. --MarSch 17:47, 13 May 2007 (UTC)

Pairing[edit]

How is this article related to pairing? It seems there is an overlap. Nageh (talk) 16:22, 26 May 2010 (UTC)

I think the question should be: Shouldn't this article be extended to cover [[module (mathematics}|module]]s? Meaning, we get R-bilinear maps, which should probably be covered in this article, and then pairing (which is evidently just an R-bilinear map) should be a redirect here. K-bilinear maps (K being a field, so this is what is currently covered by this article) are merely special cases of R-bilinear maps, which is the subject of Pairing. — Quondum 16:31, 9 September 2012 (UTC)
