Given any immersed curve T in the plane, there is a positive integer m such that for every n ≥ m there is an immersed curve Tn which has the same values of St, J+ and J− as T, and such that Tn has exactly n inscribed squares. Moreover there is k (independent of n) such that all but k many of the inscribed

Immersed plane curves have a well-defined turning number, which can be defined as the total curvature divided by 2 π. This is invariant under regular homotopy, by the Whitney–Graustein theorem – topologically, it is the degree of the Gauss map , or equivalently the winding number of the unit tangent (which … Zobacz więcej In mathematics, an immersion is a differentiable function between differentiable manifolds whose differential (or pushforward) is everywhere injective. Explicitly, f : M → N is an immersion if Zobacz więcej A regular homotopy between two immersions f and g from a manifold M to a manifold N is defined to be a differentiable function H : M … Zobacz więcej A k-tuple point (double, triple, etc.) of an immersion f : M → N is an unordered set {x1, ..., xk} of distinct points xi ∈ M with the same image … Zobacz więcej A far-reaching generalization of immersion theory is the homotopy principle: one may consider the immersion condition (the rank of the derivative is always k) as a partial differential relation (PDR), as it can be stated in terms of the partial derivatives of the function. … Zobacz więcej Hassler Whitney initiated the systematic study of immersions and regular homotopies in the 1940s, proving that for 2m < n + 1 every map f : M → N of an m-dimensional … Zobacz więcej • A mathematical rose with k petals is an immersion of the circle in the plane with a single k-tuple point; k can be any odd number, but if even must be a multiple of 4, so the figure … Zobacz więcej • Immersed submanifold • Isometric immersion • Submersion Zobacz więcej Witrynaimmersed H4-initial curves. Moreover, they prove that the surface di usion ow can drive an initially embedded curve to a self intersection. The techniques in [14, 21] seem to be restricted to two dimensions. Our methods work in any dimension and we obtain existence and uniqueness for immersed hypersurfaces.
