Maths Covectors Martin Baker Linear form. in mathematics, a linear form (also known as a linear functional, [1] a one form, or a covector) is a linear map [nb 1] from a vector space to its field of scalars (often, the real numbers or the complex numbers ). if v is a vector space over a field k, the set of all linear functionals from v to k is itself a vector space over k. Yeah, a covector is an object that "takes" a vector and returns a number, but you could define a vector as an object that "takes" a covector and returns a number! (and saying that this is all vectors and covectors can do return numbers through the inner product seems quite an understatement of what they can be used for.).

Tensors For Beginners 4 What Are Covectors Youtube Briefly, a contravariant vector is a list of numbers that transforms oppositely to a change of basis, and a covariant vector is a list of numbers that transforms in the same way. contravariant vectors are often just called vectors and covariant vectors are called covectors or dual vectors. These are really tedious to make i'm starting to lose steam. i'll make sure i finish this series, but i'm not sure how much i'll be able to manage afterward. When we take an infinitesimally small part of a manifold the vectors form the tangent space and the covectors form the cotangent space. vector elements are represented by superscripts and covector elements are represented by subscripts. coordinate independence. so lets start with a 3d global orthogonal coordinate system. Dual space. in mathematics, any vector space has a corresponding dual vector space (or just dual space for short) consisting of all linear forms on together with the vector space structure of pointwise addition and scalar multiplication by constants. the dual space as defined above is defined for all vector spaces, and to avoid ambiguity may.
