Epsilon is used with reference to sphericity. It is simply a value by which the degrees of freedom for the test of F ratio if multiplied.
When epsilon is equal to 1 sphericity is met (hence no adjustment). When it is less than 1 the assumption the the covariances and variances are violated. Greenhouse Geisser epsilon is the most common.

Yes, in statistics, the epsilon symbol is used for maximum allowable error. http://www.liaad.up.pt/~jgama/IWKDDS/Papers/p14.pdf
The greek letter closest to representing the latin letter e is epsilon (ɛ). In math's, epsilon is mainly used to represent very small positive numbers (e.g. when working with proofs), and used as the Levi-Civita symbol (a.k.a. the permutation symbol, used in tensor calculus, sometimes uses upper epsilon E, instead of lower epsilon ɛ). It is also often used in statistics and numerical analysis to represent errors.
Epsilon Tau Pi was created in 1999.
It can be just one more variable. In calculus, both delta and epsilon are used for quantities that can assume arbitrarily small values.
It's the Greek letter that looks like E (similar to €)
