    I was just opening up some pdf files on downloaded articles on string theory. As i was reading the string theory equations, (which i have no idead what it means), the stood for something called the Ghost number. So i looked up the term ghost number on wikipedia, and they talked about BRST formalism, which again had me going blank.

    can anyone briefly explain the idea of ghost numbers, though judging by the main subject, it does not seem to be an easy matter.

    thanks
