Wedge product in tensor notation

Click For Summary
SUMMARY

The discussion confirms that the wedge product in tensor notation is defined as A \wedge A \wedge A \wedge A \wedge A = \epsilon^{abcde}A_a A_b A_c A_d A_e in five dimensions. It emphasizes that A should be expressed as A \equiv A_i dx^i, establishing the basis for the wedge product. Additionally, the components of the wedge product are represented as A_{[a}A_b A_c A_d A_{e]}.

Is the following the definition of wedge product in tensor notation?

Let [tex]A \equiv A_i[/tex] be a matrix one form. Then
[tex] <br /> A \wedge A \wedge A \wedge A \wedge A = \epsilon^{abcde}A_a A_b A_c A_d A_e<br /> [/tex]?

in 5 dimensions. This question is in reference to the winding number of maps.

You should write
[tex] A \equiv A_i dx^i[/tex]

i.e. the wedge product is defined on the basis. Then your wedge product has as components

[tex] A_{[a}A_b A_c A_d A_{e]}[/tex]
