Notation in the subject is definitely a headache, but probably can't be sorted out completely in this forum. Anyway, the symbol $v$ (not greek $\nu$) is often used by Lusztig in contexts going back to his 1979 paper with Kazhdan on Hecke algebras. It may denote a square root of $q$. Even though results for Hecke algebras or quantum groups might end up with $q$-formulations, there is sometimes a subtle need to work for a while with square roots (as in the development of Kazhdan-Lusztig polynomials).
