# Weierstrass P function

Das Weierstraß-p (℘ oder ℘) ist ein stilisierter Buchstabe p und wird in der Mathematik für die Weierstraßsche elliptische Funktion verwendet. Für die Potenzmenge wird üblicherweise das großgeschriebene stilisierte P (풫) verwendet. Falls das Zeichen nicht zur Verfügung steht, wird auch das Weierstraß-p hierfür verwendet In mathematics, Weierstrass's elliptic functions are elliptic functions that take a particularly simple form. They are named for Karl Weierstrass.This class of functions are also referred to as p-functions and they are usually denoted by the symbol ℘. They play an important role in theory of elliptic functions. A ℘-function together with its derivative can be used to parameterize elliptic. The Weierstrass elliptic functions (or Weierstrass P-functions, voiced p-functions) are elliptic functions which, unlike the Jacobi elliptic functions, have a second-order pole at z=0. To specify P(z) completely, its half-periods (omega_1 and omega_2) or elliptic invariants (g_2 and g_3) must be specified. These two cases are denoted P(z|omega_1,omega_2) and P(z;g_2,g_3), respectively. The Weierstrass elliptic function is implemented in the Wolfram Language as WeierstrassP[u,.. Ist f ∈ K(L) eine gerade elliptische Funktion, deren Polstellenmenge in L enthalten ist, so existiert genau ein Polynom \begin{eqnarray}P(X)\in {\mathbb{C}}[X]\,mit\,f=P(\wp )\end{eqnarray}. Die Menge aller solcher elliptischen Funktionen bildet einen Integritätsring, der mit dem durch Ringadjunktion von ℘ an den Körper ℂ entstehenden Ring \begin{eqnarray}{\mathbb{C}}[\wp]\end.

Weierstraßsche p-Funktion Im mathematischen Teilgebiet der Funktionentheorie sind elliptische Funktionen doppeltperiodische meromorphe Funktionen. Doppeltperiodisch bedeutet, dass es zwei komplexe Zahlen ω1,ω2 gibt, die keine reellen Vielfachen voneinander sind, so dass die beiden Funktionalgleichunge

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 In mathematics, the Weierstrass function is an example of a real-valued function that is continuous everywhere but differentiable nowhere. It is an example of a fractal curve. It is named after its discoverer Karl Weierstrass. The Weierstrass function has historically served the role of a pathological function, being the first published example specifically concocted to challenge the notion that every continuous function is differentiable except on a set of isolated points.

Functions on which K. Weierstrass based his general theory of elliptic functions (cf. Elliptic function), exposed in 1862 in his lectures at the University of Berlin , . As distinct from the earlier structure of the theory of elliptic functions developed by A. Legendre, N.H. Abel and C.G. Jacobi, which was based on elliptic functions of the second order with two simple poles in the period parallelogram, a Weierstrass elliptic function has one second-order pole in the period. The graph of the Weierstrass function P The rough shape of the graph is determined by the n= 0 term in the series: cos(ˇx). The higher-order terms create the smaller oscillations. With bcarefully chosen as in the theorem, the graph becomes so jagged that there is no reasonable choice for a tangent line at any point; that is, the function is nowhere di erentiable. 4 c Brent Nelson 201 Evaluation.

Introduction Perhaps the most famous example of a continuous but nowhere di erentiable function is that of Weierstrass, w(x)= X1 k=0 ak cos(2ˇbkx); where 0 <a<1<b, with ab 1 (see ). Weierstrass proved that this function is nowhere di erentiable for some of these values of a and b, while Hardy  gave th

RHIT UNDERGRAD. MATH. J., VOL. 13, NO. 2 Namely, they served as a counterexample to the long-held belief that a continuous function in the x-y plane could only fail to be differentiable at a set of isolated points. Amazingly, Weierstrass' functions are continuous everywhere and differentiable nowhere. Later on Mandelbrot investigated the. In notation, the Weierstrass function (Weierstrass, 1872 as cited in Nelson) is defined as: Let a ∈ (0, 1) and let b be an odd integer such that ab < 1 + 3π/2. Then th

### DLMF: Weierstrass P-functio

Certainly P \mathcal{P} P contains a nonzero constant function, since all constant functions are degree-zero polynomials. To see that P \mathcal{P} P separates points, choose x x x, y ∈ [a, b] y \in [a,b] y ∈ [a, b]. Then p (t) = t − x p(t) = t-x p (t) = t − x is a polynomial with p (x) = 0 ≠ y − x = p (y). p(x) = 0 \neq y-x = p(y. * Weierstrass, Abhandlungen aus der Functionenlehre, p. 97 (see also P. du Bois-Reymond, Versuch einer Classification der willkUirlichen Functionen reeller Argumente nach ihren i4nderungen in den kleinsten Intervallen, J o u r n a 1 f iu r M a t h e m a t i k, vol. 79 (1875) Rational Functions.

The test for p >= prec + 3 can also be done at the beginning, since p really arise in the denominators of the series, we are not just dividing by it as an intermediate step of the algorithm.

The function e ax is thus an eigenvector for the Weierstrass transform. (This is in fact more generally true for all convolution transforms.) By using a=bi where i is the imaginary unit, and using Euler's identity, we see that the Weierstrass transform of the function cos(bx) is e −b 2 cos(bx. FOR p-ADIC Cn-FUNCTIONS J. Araujo and Wim H. Schikhof Ann. Math. Blaise Pascal, Vol. 1, N 1, 1994, pp. 61 - 74 Abstract. Let jK* be a non-Archimedean valued field. Then, on compact subsets of AB every K-valued Cn-function can be approximated in the Cn-topology by polynomial functions (Theorem 1.4). This result is extended to a Weierstrass-Stone type theorem (Theorem 2.10). INTRODUCTION.

The transformation of his conception of an analytic function from a differentiable function to a function expansible into a convergent power series was made during this early period of Weierstrass's mathematical activity

We explain which Weierstrass ${\wp}$-functions are locally definable from other ${\wp}$-functions and exponentiation in the context of o-minimal structures. The proofs make use of the predimension method from model theory to exploit functional transcendence theorems in a systematic way. Keywords . o-minimality local definability Weierstrass ℘-function predimension MSC classification. Primary. functions, frequently applied in the study of hypergeometric series, were named in his honor. In developments of the theory of elliptic functions, modern authors mostly follow Karl Weier- strass. The notations of Weierstrass's elliptic functions based on his p-function are conve-nient, and any elliptic function can be expressed in terms of these. The elliptic functions introduced by Carl. tic functions of the form g = 1/p, where p is the Weierstrass elliptic function, on triangular lattices. These functions can be parametrized by C - {0}, and they all have a superattracting fixed point at zero and three other distinct critical values. We prove that the Julia set of g is either Cantor or connected, and we obtain examples of each type. 1. Introduction Quadratic polynomials always. WEIERSTRASS TYPE FUNCTIONS TIAN-YOU HU AND KA-SING LAU ABSTRACT. A new type of fractal measures Xs 1 < s < 2, defined on the subsets of the graph of a continuous function is introduced. The J-dimension defined by this measure is 'closer' to the Hausdorff dimension than the other fractal dimensions in recent literatures. For the Weierstrass type functions de- fined by W(x) = A-aig(Aix), where A.
