  • Tensors Explained: Scalars, Vectors, Matrices Math
    Tensor Product Properties Definition: A tensor product of vector spaces is a vector space structure on the Cartesian product that satisfies This means a tensor product is a freely generated vector space of all pairs that satisfies some additional conditions such as linearity in each argument, i e bilinearity, which justifies the name product
  • An Introduction to Tensors - Mathematics Stack Exchange
    In mathematics, tensors are one of the first objects encountered which cannot be fully understood without their accompanying universal mapping property 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 spaces The tensor product provides a
  • 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
  • How would you explain a tensor to a computer scientist?
    A tensor extends the notion of a matrix analogous to how a vector extends the notion of a scalar and a matrix extends the notion of a vector A tensor can have any number of dimensions, each with its own size A $3$ -dimensional tensor can be visualized as a stack of matrices, or a cuboid of numbers having any width, length, and height
  • 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?
  • What even is a tensor? - Mathematics Stack Exchange
    I'm an electrical engineer, and thus don't often interact with the types of mathematics that involve tensors But when I try to get a deeper understanding of certain things that I do interact with, I
  • 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)
  • terminology - What is the history of the term tensor? - Mathematics . . .
    tensor - In new latin tensor means "that which stretches" The mathematical object is so named because an early application of tensors was the study of materials stretching under tension
  • Definition of Second-Order Tensor by Jim Adrian - Physics Forums
    A second-order tensor is comprised at least of a two-dimensional matrix, as an nth-order tensor is comprised at least of an n-dimensional matrix, but what else is in the formal definition A scientific definition needs to name the term being defined, and describe the meaning of that term only by reference to meanings previously established
