Immersion (mathematics)
ID: immersion-mathematics
In mathematics, particularly in the field of differential topology, an **immersion** is a type of function between differentiable manifolds. Specifically, if we have two differentiable manifolds \(M\) and \(N\), a function \(f: M \to N\) is called an immersion if its differential \(df\) is injective at every point in \(M\).
