Conflicting definitions
[edit]The Definition section treats a dyadic as a covariant tensor, whereas the Example section offers an alternative definition according to which a dyadic is a mixed-valence tensor. The article Dyadic product offers a third definition, according to which a dyadic is simply the tensor product of two vectors, and thus a contravariant tensor. It might be helpful to standardize these pages to one definition, perhaps with a note on each explaining any alternative possibilities that may be common in the literature. I'm afraid I don't know whether one of them is more standard, or of so which. Dependent Variable (talk) 00:17, 16 October 2010 (UTC)
Transposes
[edit]It looks as though the matrix notation used to express the "identity dyadic tensor" assumes i = (1 0 0) etc., that is, that the basis vectors are expressed as rows of components, rather than columns. If so, it could do with a word of explanation to avoid anyone reading it as I = 3. Dependent Variable (talk) 00:17, 16 October 2010 (UTC)
