https://www.mathconverse.com/en/Definitions/Epsilon/

In mathematics: (particularly calculus), an arbitrarily small positive quantity is commonly denoted ε; see (ε, δ)-definition of limit. In reference to this, the late mathematician Paul Erdős also used the term epsilons to refer to children. Hilbert introduced epsilon terms εχ. ... It is used to represent the Levi-Civita symbol.
