In
mathematics, the adjective
trivial is frequently used for
objects (for example,
groups or
topological spaces) that have a very simple structure. The noun
triviality usually refers to a simple technical aspect of some proof or definition. The origin of the term in mathematical language comes from the medieval
trivium curriculum. The antonym
nontrivial is commonly used by engineers and mathematicians to indicate a statement or theorem that is not obvious or easy to prove.
