  1. What, Exactly, Is a Tensor? - Mathematics Stack Exchange

    Some tensors correspond to geometric objects or primitives. As I said, vectors can be thought of as very simple tensors. Some other tensors correspond to planes, volumes, and so on, formed …

  2. An Introduction to Tensors - Mathematics Stack Exchange

    Before talking about tensors, one needs to talk about the tensor product of vector spaces. You are probably already familiar with the direct sum of vector spaces. This is an addition operation on …

  3. Tensors, what should I learn before? - Mathematics Stack Exchange

    May 23, 2019 · Here I will be just posting a simple questions. I know about vectors but now I want to know about tensors. In a physics class I was told that scalars are tensors of rank 0 and …

  4. What is exactly the relation between vectors, matrices, and tensors ...

    Nov 24, 2016 · In an introduction to Tensors it is said that tensors are a generalization of scalars, vectors and matrices: Scalars are 0-order tensors, vectors are 1-order tensors, and matrices …

  5. What are the Differences Between a Matrix and a Tensor?

    Jun 5, 2013 · 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?

  6. Are there any differences between tensors and multidimensional …

    Feb 5, 2015 · The short of it is, tensors and multidimensional arrays are different types of object; the first is a type of function, the second is a data structure suitable for representing a tensor in …

  7. Conceptual difference between Covariant and Contravariant tensors

    Nov 5, 2021 · I am having some confusion over the concept of covariant and contravariant vectors. Most text books on tensors define contravariant vectors/tensors as objects whose …

  8. What does the dot product of a tensor and a vector represent?

    Using this fact we can identify the space of 2-tensors, $V\otimes V$ with the space of linear maps $V\to V$ by sending a pure 2-tensor $a\otimes b$ to the linear map $L_ {ab}$ taking $v\to …

  9. What is the conceptual idea behind raising and lowering indices?

    The use of indices for tensors originates from notation for matrices and vectors but extends consistently and beautifully first to abstract vector spaces and then to tensors and tensor …

  10. How does the fourth order Identity tensor look like

    Dec 1, 2022 · Note that the $\I$ in your post actually equals $\G$, which is one of the isotropic tensors but not the identity tensor (although it does yield a scalar multiple of the identity matrix).
