Twistor string theory
Twistor string theory is an equivalence between N = 4 supersymmetric Yang–Mills theory and the perturbative topological B model string theory in twistor But twistor space is chiral (handed) with left- and right-handed objects treated differently. wikipedia.org

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...
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!

A few general questions on the Penrose transform Let us consider the Bateman or Whittaker's pioneering examples of a Penrose transform. Starting from a holomorphic function on an open subset of twistor space, they con...
I found the explanation in Huggett and Tod's book, "Introduction to Twistor theory", to be very clear and down to earth (it was recommended to me by D. Using homogeneous coordinates on (projective) twistor space, a la Penrose, and using the integral formula, one can then answer all my questions.
