In mathematics, a point x is called an isolated point of a subset S (in a topological space X) if x is an element of S and there exists a neighborhood...

mathematics, a space of points is typically treated as a set, a point set. An isolated point is an element of some subset of points which has some neighborhood...

In chess, an isolated pawn is a pawn that has no friendly pawn on an adjacent file. Isolated pawns are usually a weakness because they cannot be protected...

metric space with no isolated point is uncountable. (If X {\displaystyle X} is a nonempty countable metric space with no isolated point, then each singleton...

An isolated ground (IG) (or Functional Earth (FE) in European literature) is a ground connection to a local earth electrode from equipment where the main...
