Generalized Weierstrass form

The classical theory of the Weierstrass transform is extended to a generalized function space which is the dual of a testing function space consisting of purely entire functions with certain growth conditions developed by Kenneth B. Howell. An inversion formula and characterizations for this transform are obtained. A comparative study with the existing literature is also undertaken Within the generalized Weierstrass inducing the functional W has a very simple form. Indeed, by using of (2.3) and (2.4), one gets Indeed, by using of (2.3) and (2.4), one gets W = 4 ∫ p 2 d z d ¯ z GENERALIZED WEIERSTRASS TRANSFORM 509 Theorem 7.3.5, p. 213 . On the other hand the Weierstrass transform ofx. bounded functions, L p-functions, and certain other functions with pre-scribed growth conditions are all characterized by Hirshman and Widder wx3 . For other types of Weierstrass transforms on single or multidimen-sional spaces we refer to 2 .w ancestor, generalized the definition of Weierstrass function as the following form named by WMF: w(t)= +∞ n=−∞ (1−eiγnt)eiφn γ(2−D)n, (1) where 1 <D<2, γ>1andφn is an arbi-trary.

Generalized Weierstrass representations of surfaces with the constant Gauss curvature in pseudo-Riemannian three-dimensional space forms The generalized Weierstrass formulae of the surfaces in R 3 with coordinates X 1, X 2, X 3 are of following form (e.g. Ref. ) X 1 + i X 2 = i ∫ Γ (φ ̄ 2 d z − ψ ̄ 2 d z ̄), X 1 − i X 2 = i ∫ Γ (ψ 2 d z − φ 2 d z ̄), X 3 = ∫ Γ (ψ ̄ φ d z + φ ̄ ψ d z ̄), where Γ is a contour in C, and φ, ψ satisfy φ z = p ψ, ψ z ̄ = − p φ In mathematics, the Weierstrass transform of a function f : R → R, named after Karl Weierstrass, is a smoothed version of f(x) obtained by averaging the values of f, weighted with a Gaussian centered at x. The graph of a function f (x) (black) and its generalized Weierstrass transforms for five width (t) parameters The complex-analytic approach to constructing minimal surfaces carried out by Weierstrass and Enneper has since been extended to create conformal parametrizations of minimal and more general surfaces, including Euclidean, spacelike, and timelike surfaces in three-dimensional Euclidean and Lorentz spaces. In this work, we present a Lie-algebraic formulation that unites these representations into one coherent framework and completes the formulas in the general timelike case. Integrable moving.

In mathematical analysis, the Weierstrass approximation theorem states that every continuous function defined on a closed interval can be uniformly approximated as closely as desired by a polynomial function. Because polynomials are among the simplest functions, and because computers can directly evaluate polynomials, this theorem has both practical and theoretical relevance, especially in polynomial interpolation. The original version of this result was established by Karl. Introduction to the Weierstrass functions and inverses. General. Historical remarks. The Weierstrass elliptic functions are identified with the famous mathematicians N. H. Abel (1827) and K. Weierstrass (1855, 1862). In the year 1849, C. Hermite first used the notation ℘123 for the basic Weierstrass doubly periodic function with only one double pole. The sigma and zeta Weierstrass functions. In mathematics, the Weierstrass transform of a function f : R → R, named after Karl Weierstrass, is the function F defined by The graph of a function f (x) (gray) and its generalized Weierstrass transforms for t = 0.2 (red), t = 1 (green) and t = 3 (blue). The standard Weierstrass transform F (x) is given by the case t = 1, the green graph In this chapter, some recent advances in the area of generalized Weierstrass representations will be given. This is an approach to the theory of surfaces in Euclidean three space. Weierstrass representations permit the explicit construction of surfaces in the designated space. The discussion proceeds in a novel and introductory manner. The inducing formulas for the coordinates of a surface are derived and important conservation laws are formulated. These lead to the inducing. Generalized Weierstrass semigroups of certain curves of the form f (y) = g (x) Let X f , g be a curve over F q having a plane model given by an affine equation of type f ( y ) = g ( x ) , where f ( T ) , g ( T ) ∈ F q [ T ] with deg ⁡ ( f ( T ) ) = a and deg ⁡ ( g ( T ) ) = b satisfying gcd ( a , b ) = 1

Generalized Weierstrass System which determine the form of a given membrane surface, as in a liquid crystal. In an equilibrium state, the energy of any physical system must be minimized. One usually writes down a shape energy function Fin terms of the basic parameters and then minimizes it, and the result is a shape equation. An example of such a shape function is given by F= 1 2 k c Z (2H. (char(K) = 2) we use the following equation, called the generalized Weierstrass equation: y2 + a 1xy+ a 3y= x3 + a 2x2 + a 4x+ a 6 where a i 2K. It is shown in [4, Section 2.1] that if char(K) 6= 2 then there is a linear change of variables after which the generalized Weierstrass equation takes the form (2.1). We also use a the following equation for elliptic curves in this document The metric and the mean curvature on Uhave the form ds2 = e2α(dx2 +dy2), H= 2u eα, eα= |ψ2 1|+|ψ22|. (2.6) This construction is known as the Weierstrass representation. It was originally intro-duced by Weierstrass to describe minimal surfaces (corresponding to u = 0) and later extended by arbitrary surfaces by Eisenhart in [8]. It was first written in the above form

maps a suitably restricted function f( r) into an analytic function on a strip a, < Re s < a2 in the complex s-plane. Other names for it are the Gauss transformation [2], the Gauss-Weierstrass transformation [3, p. 578], and the Hille transformation [4]. The objective of this work is to extend the Weierstrass transformation and a certain inversion formula [1, p. 191] to allow f(Qr) to be a. A representation of generalized Weierstrass formulae for an immersion of generic surfaces into a 4-dimensional complex space in terms of spinors treated as minimal left ideals of Clifford algebras is proposed. The relation between integrable deformations of surfaces via mVN-hierarchy and integrable deformations of spinor fields on the surface is also discussed In this work we study the generalized Weierstrass semigroup $\widehat{H} (\mathbf{P}_m)$ at an $m$-tuple $\mathbf{P}_m = (P_{1}, \ldots , P_{m})$ of rational points on certain curves admitting a plane model of the form $f(y) = g(x)$ over $\mathbb{F}_{q}$, where ${f(T),g(T)\in \mathbb{F}_q[T]}$. In particular, we compute the generating set $\widehat{\Gamma}(\mathbf{P}_m)$ of $\widehat{H} (\mathbf{P}_m)$ and, as a consequence, we explicit a basis for Riemann-Roch spaces of divisors with.

When we construct one-point algebraic geometry codes, we have to find a basis of L(mQ) having pairwise distinct pole orders at Q.If we have the defining equation of a hyperelliptic curve in the Weierstrass form, then we can easily find such a basis of L(mQ) for the unique place Q at infinity. This fact can be generalized for an arbitrary curve as follows
