In the context of Wikipedia and other collaborative online encyclopedias, a "stub" is a type of article that is considered incomplete or lacking in detail. A "Number theory stub" specifically refers to a very brief article related to the field of number theory—a branch of pure mathematics devoted to the study of the integers and their properties. Stubs typically provide only basic information or a limited overview of the topic, and they are often marked with a template indicating that they need expansion.
