In mathematics, a '''modular invariant''' of a [[group (mathematics)|group]] is an invariant of a [[finite group]] [[groupGroup action (mathematics)|acting]] on a [[vector space]] of positive characteristic (usually dividing the order of the group). The study of modular invariants was originated in about 1914 by {{harvtxt|Dickson|2004}}.
