WebTools. In mathematics, a linear form (also known as a linear functional, [1] a one-form, or a covector) is a linear map 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 with addition ...

WebJul 15, 2015 · As you might guess based on the fact that V ∗ is called the "dual" of V, in mathematics and mathematical physics the covector of a vector v is called the "dual" of v. In physics, vectors are often denoted e.g. v . The v is a label which names the vector. In other words, v is like v → . The associated covector is denoted v . WebApr 30, 2024 · you are immediately able to take the covariant derivative ∇ f of a scalar field, which coincides with its exterior derivative d f. ∇ f = d f = ∑ i ∂ i f ω i. where ω i are the basis covector fields. Obviously this is a covector field. Then the derivative of f in the direction of a vector v admits the following notations:
