👉 In mathematics, a conservancy is a set of points in a space that are closed under certain operations. In other words, it's a subset of the space that contains all its limit points and the set of accumulation points. A set is said to be a conservancy if for each point x in the set, there exists some open ball B(x) centered at x such that B(x) does not contain any point y in the conservancy. This means that every accumulation point of the set
