Derivative of a wedge product
WebThe wedge product of two vectors u and v measures the noncommutativity of their tensor product. Thus, the wedge product u ∧ v is the square matrix defined by Equivalently, Like the tensor product, the wedge product is defined for two vectors of arbitrary dimension. Notice, too, that the wedge product shares many properties with the cross product. WebThe exterior product of two 1-forms is a 2-form: sage: s = a.wedge(b) ; s 2-form a∧b on the 2-dimensional differentiable manifold M sage: s.display(eU) a∧b = (-2*x^2*y - x) dx∧dy sage: s.display(eV) a∧b = (1/8*u^3 - 1/8*u*v^2 - 1/8*v^3 + 1/8* (u^2 + 2)*v + 1/4*u) du∧dv Multiplying a 1-form by a scalar field results in another 1-form:

If f: M→R is a differentiable function, then we define the exterior derivative of fto be the 1-form dfwith the property that for any x∈M, v∈T xM, df x(v) = v(f). A local basis for the space of 1-forms on M can be described as before in
