Fiber (mathematics)

Summary

In mathematics, a fiber (US English) or fibre (British English) of a map or function f:X→Yf:X\to Y is an equivalence class in X for the relation of having the same image under f. If y is that image, then this fiber equals the inverse image f−1(y)={x∈X:f(x)=y}f^{-1}(y) = \{ x\in X : f(x) = y \} of yy and is called the fiber of f over y.
