Wedge and common notation for "a line between two points" I'm using a somewhat old presentation from 2011 that covers twistor geometry. It uses the notation "$L = Z_1 \wedge Z_2$" to suggest that the line $L$ is the "join of the twistors $Z_1$ and $Z_2$, which are simply points in this twistor space. However, I have always learned that the line between two points, which is essentially what this is, is just given by writing $L=Z_1Z_2$. Is there any difference between the two? Does this wedge notation have any other meaning that I'm not aware of? Is there any other standard notation that I have omitted? EDIT: For reference, the full presentation is available at < See the screenshot of the relevant section here. EDIT2: Found the answer, will accept in 2 days when I'm allowed to! See below.

Answer lies in Boolean algebra. Why is $\wedge$ a minimum and $\vee$ a maximum? and < are the resources used. Turns out that in Boolean notation $A \wedge B = AB$, who'd've thunk'd it!
