Dyadics - Wikipedia
WEBIn mathematics, specifically multilinear algebra, a dyadic or dyadic tensor is a second order tensor, written in a notation that fits in with vector algebra. There are numerous ways to multiply two Euclidean vectors. The dot product takes in two vectors and returns a scalar, while the cross product [a] returns a pseudovector.
The Dyad and -adic Forms - Duke University
WEBA dyad is an interesting object. Each term appears to be formed out of the ordinary multiplicative product of two numbers (which we can easily and fully compute and understand) followed by a pair of unit vectors that are juxtaposed. What, exactly does this juxtaposition of unit vectors mean?
Dyadic -- from Wolfram MathWorld
WEBAug 22, 2024 · A dyadic, also known as a vector direct product, is a linear polynomial of dyads consisting of nine components which transform as. Dyadics are often represented by Gothic capital letters. The use of dyadics is nearly archaic since tensors perform the same function but are notationally simpler.
WEBThe tensor product of two vectors represents a dyad, which is a linear vector transformation. A dyad is a special tensor – to be discussed later –, which explains the name of this product. Because it is often denoted without a symbol between the two vectors, it is also referred to as the open product. The tensor product is not commutative.
WEBIn general, we can specify a unit vector u, at any location we wish, to point in any direction we please. In order to construct another vector from the unit vector, we multiply u
WEBDyadic Green’s Function. As mentioned earlier the applications of dyadic analysis facilitates simple manipulation of field vector calculations. The source of electromagnetic fields is the electric current which is a vector quantity.

WEBMay 6, 2018 · Suppose a vector a . It can be written as: ∑i ei→ ei→ ⋅a = 1 ⋅ a. where ei→ are unit basis vectors. I can't figue out what is 1 (called dyadic) and how to obtain it from ei→ei→. Reading Wikipedia gave no undestanding.
Dyad -- from Wolfram MathWorld
WEBAug 22, 2024 · Dyads extend vectors to provide an alternative description to second tensor rank tensors. A dyad D (A,B) of a pair of vectors A and B is defined by D (A,B)=AB. The dot product is defined by A·BC= (A·B)C (1) AB·C=A (B·C), (2) and the colon product by AB:CD=C·AB·D= (A·C) (B·D). (3)
WEBvector function is denoted by F. Geometrically, it is represented by a line with an arrow in a three-dimensional space. The length of the line corresponds to its magnitude, and the direction of the line represents the direction of the vector function.
