Let $S\subseteq\mathbb{R}^n$. We say that $\vec{a}$ is an accumulation point of $S$ if $\vec{a}$ is a limit point of $S\backslash\{\vec{a}\}$.
The set of all accumulaion points is denoted $S^a$.
If a point $\vec{a}\in S\backslash S^a$, then we call this an isolated point.
The set of all accumulaion points is denoted $S^a$.
If a point $\vec{a}\in S\backslash S^a$, then we call this an isolated point.
