- What Is a Tensor? The mathematical point of view. - Physics Forums
A tensor itself is a linear combination of let’s say generic tensors of the form In the case of one doesn’t speak of tensors, but of vectors instead, although strictly speaking they would be called monads
- What is a Rank 3 Tensor and Why Does It Matter? - Physics Forums
A rank 3 tensor inputs three generalized vectors (i e either a vector or their dual vector), and spits out a scalar One can also think of it as inputting 2 generalized vectors (or a rank 2 tensor), and outputting a vector, or inputting 1 generalized vector, and outputing 2 vectors (or a rank 2 tensor)
- What are the Differences Between a Matrix and a Tensor?
What is the difference between a matrix and a tensor? Or, what makes a tensor, a tensor? I know that a matrix is a table of values, right? But, a tensor?
- All About the Einstein Field Equations - Physics Forums
Mathematically, the EFE relate the Ricci curvature tensor , the metric tensor , and the stress-energy tensor , incorporating the Einstein constant Fast Facts Einstein’s Big Reveal: Albert Einstein first presented the Einstein Field Equations in 1915
- What exactly is a tensor product? - Mathematics Stack Exchange
This is a beginner's question on what exactly is a tensor product, in laymen's term, for a beginner who has just learned basic group theory and basic ring theory I do understand from wikipedia th
- understanding of the tensor product of vector spaces
Isn't it easier to just define tensor algebra as the largest model (in the sense of a universal property) of the unital associative algebra oer k k that contains V V as a subspace? Tensor product of vector spaces becomes easier to understand then
- manifolds - Difference Between Tensor and Tensor field? - Mathematics . . .
A scalar is a tensor of order or rank zero , and a scalar field is a tensor field of order zero A vector is a tensor of order or rank one , and a vector field is a tensor field of order one Some additional mathematical details Rn R n is a vector space representing the n-tuples of reals under component-wise addition and scalar multiplication
- Is current truly a scalar quantity or a tensor? - Physics Forums
TL;DR Summary From what i know all quantities are tensors , divided into rank 0,rank 1 ,rank 2 , rank 3 rank ( n )according to their components which is 3^n Current is supposed to be a scalar quantity right? It does not follow vector rules Our book says it is a tensor quantity (ofcourse yes) but my question is "Is current truly a scalar quantity" ? If a bunch of electron were to drift
