Ok first a warning, this may be completely bogus as it was a symbol (or actually a notation) that I didn't recognize in a blackboard full of equations from a stupid "teen" movie. It may have been completely meaningless.
I was visiting a friend today and her daughter was playing a DVD of some dumb kids/teen movie. One thing caught my eye when they showed the "geeks" working at a blackboard full of infinite sum type identities. Curiosity got the better of me and I got here to pause it to so I could take a look and see if they were real identities or just gibberish (as equations in the background on blackboards in movies sometimes are).
Well I wasn't able to tell if they were gibberish or not because there was one bit of notation in all the equations that I'm not familiar with. As part of an infinite sum over "n" it had terms like,
[tex] \left( \frac{1}{2} \right)^3_n [/tex].
Does anyone recognize that or is it just nonsense?
