Before we prove the theorem, we require the following lemma: Lemma (The Weierstrass M-test). Let (E;d) be a metric space, and for each n2N let f n: E !R be a function.

The plots above show for (red), 3 (green), and 4 (blue). The function was published by Weierstrass but, according to lectures and writings by Kronecker and Weierstrass, Riemann seems to have claimed already in 1861 that. In der Mathematik bezeichnet man als Weierstraß-Funktion ein pathologisches Beispiel einer reellwertigen Funktion einer reellen Variablen. Diese Funktion hat die Eigenschaft, dass sie überall stetig, aber nirgends differenzierbar ist. Sie ist nach ihrem Entdecker Karl Weierstraß benannt. Historisch gesehen liegt ihre Bedeutung darin, dass sie das erste befriedigende Beispiel für eine nirgends differenzierbare Funktion ist. Weierstraß war allerdings nicht der erste, der eine.

In fact, it turns out that most continuous functions are non-differentiable at all points. (To understand what this.

Strangely, the case of the graph of the Weierstrass function, introduced in 1872 by K. Weierstrass, which presents self similarity properties, does not seem to have been considered anywhere.

Definition We treat the Weierstrass ℘ function associated to a lattice Λ ⊂ C as a principal value distribution on the torus C/Λ and compute its Fourier coefficients.

Consider the classical Weierstrass function. W ( x) = ∑ n = 1 ∞ e i 2 n x 2 n. It is a well-known result that this function is nowhere differentiable (Hardy, TAMS 1916, Thm 1.31).

The Weierstrass nowhere differentiable function, and functions constructed from similar infinite series, have been studied often as examples of functions whose graph is a fractal.
