I can't seem to find anything which explains what $\Omega_\pm$ means...

If that's true then that article deserves the purifying heat of the fire and its author(s) deserve to be kindly

For anyone trying to be the worst maths-paper writer, I bring you the following excellent article of prof. J.S. Milne for authors:
