  • What Is a Tensor? The mathematical point of view.
    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, Exactly, Is a Tensor? - Mathematics Stack Exchange
    Every tensor is associated with a linear map that produces a scalar For instance, a vector can be identified with a map that takes in another vector (in the presence of an inner product) and produces a scalar

  • Is current truly a scalar quantity or a tensor? • Physics Forums
    Electric field is present The net movement of electrons would flow in direction opposite to the electric field yes But if we were to take a small cross section of the conductor and say 3 electrons are moving in slightly different directions would that not mean that it has 3 components to the
  • Element-wise (or pointwise) operations notation?
    Is there a notation for element-wise (or pointwise) operations? For example, take the element-wise product of two vectors x and y (in Matlab, x * y, in numpy x*y), producing a new vector of same
  • Stress-energy tensor and energy momentum conservation clarification
    The discussion centers on the stress-energy tensor in general relativity and its implications for energy and momentum conservation The confusion arises regarding the necessity of an external force term, F α, in the conservation equations when considering interactions with external systems
  • What does the dot product of a tensor and a vector represent?
    The meaning of the dot product of two vectors has been well explained below: What does the dot product of two vectors represent? What is physical interpretation of dot product? [duplicate] But, what is the meaning of the dot product of a tensor and a vector, if there is any?
  • Deriving displacement tensor from Hencky (true) strain tensor
    The Hencky strain, AKA true strain, logarithmic strain, can be related to displacement tensor as follows: However, Hencky strain is typically done only for principal strains This can be easily shown by actually trying to calculate the full displacement tensor using the above definition: Typically we have E<1, and if I am looking at a strain rate, then it is E<<1, the above equation will
