In mathematics, a circle with a plus sign inside typically represents the operation of direct sum, often used in linear algebra and abstract algebra. It indicates the combination of two vector spaces or algebraic structures, where each retains its own properties while contributing to a larger structure. This notation can also appear in other contexts, like topology or category theory, to signify a specific type of addition or combination.
