trivial The term is used variously in mathematics. It may refer to the easiness of a conclusion. It also refers to simple or straightforward examples: the trivial group (or subgroup) consists only of the identity element; the trivial set is the empty set; the trivial subspace consists only of the zero vector; the trivial topology on a set consists only of the set itself and the empty set; the trivial factors of an integer n are ±1, ±n.
