Abstract Vector Spaces, Linear Transformations, and Their
... A subset β ⊆ V is called a (Hamel) basis if it is linearly independent and span(β) = V . We also say that the vectors of β form a basis for V . Equivalently, as explained in Theorem 1.13 below, β is a basis if every nonzero vector v ∈ V is an essentially unique linear combination of vectors in β. In ...

... bicategories. In Vect k - Mod the pseudomonoids include monoidal k-linear categories such as Vect k itself. The Frobenius requirement is related to the notion of star-autonomy due to Michael Barr. Every rigid (autonomous, compact) monoidal category is star-autonomous. In particular, Vect k is Froben ...

Cartesian tensor
In geometry and linear algebra, a Cartesian tensor uses an orthonormal basis to represent a tensor in a Euclidean space in the form of components. Converting a tensor's components from one such basis to another is through an orthogonal transformation.The most familiar coordinate systems are the two-dimensional and three-dimensional Cartesian coordinate systems. Cartesian tensors may be used with any Euclidean space, or more technically, any finite-dimensional vector space over the field of real numbers that has an inner product.Use of Cartesian tensors occurs in physics and engineering, such as with the Cauchy stress tensor and the moment of inertia tensor in rigid body dynamics. Sometimes general curvilinear coordinates are convenient, as in high-deformation continuum mechanics, or even necessary, as in general relativity. While orthonormal bases may be found for some such coordinate systems (e.g. tangent to spherical coordinates), Cartesian tensors may provide considerable simplification for applications in which rotations of rectilinear coordinate axes suffice. The transformation is a passive transformation, since the coordinates are changed and not the physical system.
