Differentiability of fractal curves

  title={Differentiability of fractal curves},
  author={Christoph Bandt and A. S. Kravchenko},
A self-similar set that spans can have no tangent hyperplane at any single point. There are lots of smooth self-affine curves, however. We consider plane self-affine curves without double points and with two pieces. There is an open subset of parameter space for which the curve is differentiable at all points except for a countable set. For a parameter set of codimension one, the curve is continuously differentiable. However, there are no twice differentiable self-affine curves in the plane… Expand

Pointwise regularity of parameterized affine zipper fractal curves
We study the pointwise regularity of zipper fractal curves generated by affine mappings. Under the assumption of dominated splitting of index-1, we calculate the Hausdorff dimension of the level setsExpand
On transverse hyperplanes to self-similar Jordan arcs.
We consider self-similar Jordan arcs γ in \(\mathbb{R}^{d}\), different from a line segment and show that they cannot be projected to a line bijectively. Moreover, we show that the set of points x ∈Expand
Self-affine sets in analytic curves and algebraic surfaces
We characterize analytic curves that contain non-trivial self-affine sets. We also prove that compact algebraic surfaces cannot contain non-trivial self-affine sets.
Novel method of fractal approximation
We introduce new method of optimization for finding free parameters of affine iterated function systems (IFS), which are used for fractal approximation. We provide the comparison of effectiveness ofExpand
On Weak Separation Property for Affine Fractal Functions
We show that a fractal affine function $f(x)$ defined by a system $\mathcal S$ which does not satisfy weak separation property is a quadratic function.
We show that a fractal affine function f(x) defined by a system S which does not satisfy weak separation property is a quadratic function.


Topology and separation of self-similar fractals in the plane
Even though the open set condition (OSC) is generally accepted as the right condition to control overlaps of self-similar sets, it seems unclear how it relates to the actual size of the overlap. ForExpand
On the geometric structure of the limit set of conformal iterated function systems
We consider infinite conformal iterated function systems on R. We study the geometric structure of the limit set of such systems. Suppose this limit set intersects some l–dimensional C–submanifoldExpand
Dimension and measures on sub-self-affine sets
We show that in a typical sub-self-affine set, the Hausdorff and the Minkowski dimensions coincide and equal the zero of an appropriate topological pressure. This gives a partial positive answer toExpand
On Selfsimilar Jordan Curves on the Plane
We study the attractors of a finite system of planar contraction similarities Sj (j=1,...,n) satisfying the coupling condition: for a set {x0,...,xn} of points and a binary vector (s1,...,sn), calledExpand
Additive functions of intervals and Hausdorff measure
Consider bounded sets of points in a Euclidean space R q of q dimensions. Let h(t) be a continuous increasing function, positive for t >0, and such that h (0) = 0. Then the Hausdroff measure h–mE ofExpand
