# Wedge product of vector fields

Can somebody explain me step by step how can I compute the wedge product $X\wedge Y$ of two vector fields, $X,Y$, in $\mathbb{C}^2$?

We can consider $$X=X_1\partial_x+X_2\partial_y$$ and $$Y=Y_1\partial_x+Y_2\partial_y$$

Please!

I take it $x$ and $y$ are complex coordinates? –  Muphrid May 14 '13 at 20:25
Yes @Muphrid they are complex –  OhMyGod May 14 '13 at 20:25

Expand out. $\ \ e_i \wedge e_i=0, \ \ e_i \wedge e_j=-e_j \wedge e_i$

$e_1=\partial_x, e_2=\partial_y \\X\wedge Y=X_1Y_1e_1\wedge e_1+X_1Y_2e_1\wedge e_2+X_2Y_1e_2\wedge e_1+X_2Y_2e_2\wedge e_2\\ =(X_1Y_2-X_2Y_1)e_1\wedge e_2=(X_1Y_2-X_2Y_1) \partial_x \wedge \partial_y$

What does the objecct $\partial_x\wedge\partial_y$ means? –  OhMyGod May 14 '13 at 22:57
