Derivative of a wedge product
WebDec 19, 2024 · The wedge product is defined for forms, so I interpret that each $dx^0$, $dx^1$, $\ldots$, $dx^ {n-1}$ is a form. My problem is that, by following the book, they should be exterior derivatives of $x^0, x^1, \ldots, x^ {n-1}$, but how that would be possible if he defined the exterior derivative as an operator on forms? WebJul 9, 2024 · Exterior Derivative of Wedge Product and "Double Antisymmetrization" Asked 5 years, 8 months ago Modified 5 years, 8 months ago Viewed 456 times 0 I have the following question: in Carroll's book we're asked to show that d ( ω ∧ η) = ( d ω) ∧ η + ( − 1) q ω ∧ ( d η) For a p -form ω and q -form η.

WebJan 10, 2024 · I prove that the wedge product of an n-dimensional 2-form and 1-form is completely antisymmetric in any number of dimensions n 2 and therefore a 3-form. Then we meet the exterior derivative They both involve the ghastly total antisymmetrisation operation [] on indices. It is defined back in his equation (1.80) as This led on to Exercise 2.08 WebThe exterior derivative of the wedge product of two one-forms. 🔗 Remark 4.3.8. In , R 3, the graded product rule can be split into the four following non-vanishing cases. If ω = f is a zero-form (in which case we write f ∧ η = f η as usual when multiplying with a function) and η = g is a zero-form, then d ( f g) = d ( f) g + f d ( g).
WebA vector field is an operator taking a scalar field and returning a directional derivative (which is also a scalar field). ... However, the higher tensors thus created lack the interesting features provided by the other type of product, the wedge product, namely they are not antisymmetric and hence are not form fields.
