Generic point

In topology, a **generic point** is a concept used to describe a point that represents a subset of a topological space in a broad or "generic" sense. Specifically, a point \( x \) in a topological space \( X \) is called a generic point of a subset \( A \) of \( X \) if every open set containing \( x \) intersects \( A \) in a non-empty set.
