{wiki=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\\).
