* The lowercase iota symbol is sometimes used to write the [[imaginary unit]], but more often Roman [[i]] or [[j]] is used.
* In [[mathematics]], the [[inclusion map]] of one space into another is sometimes denoted by the lowercase iota.
* In [[logic]], the lowercase iota denotes the [[Definite description#Symbolic form|definite descriptor]].
* The lowercase iota symbol has Unicode code point U+03B9 and the uppercase U+0399.
