A **fixed-point space** is a concept commonly used in mathematics, particularly in topology and analysis. It generally refers to a setting in which a function has points that remain unchanged when that function is applied. More formally, if \( f: X \to X \) is a function from a space \( X \), then a point \( x \in X \) is said to be a **fixed point** of \( f \) if \( f(x) = x \).
