Closed Euclidean Ball: Also known as
Some sources refer to a closed Euclidean ball of $n$ dimensions merely as an $n$-ball, as they are not interested in contexts other than real Euclidean spaces.
However, it needs to be remembered that a ball has a more general definition in the context of a general metric space.
