Boundary Values of (Slowly Increasing) Holomorphic Functions [PDF]

open access: yes, 1994
In this paper, we investigate the conditions that (slowly increasing) holomorphic functions F_±(z) on C_± have the boundary values F_±(x±i0)=lim F_±(x±iε) in the sense of cl([a,b]) (or, cl(D)) and define the Sato (Fourier) hyperfunction f(x)=F_+(x+iO ...

Quantum Field Theory in Terms of Fourier Hyperfunctions

open access: yesPublications of the Research Institute for Mathematical Sciences, 1976
The Wightman axioms are extended to the quantum field theory in terms of Fourier hyperfunctions. The support concept of hyperfunctions is crucial for the formulation of locality and spectral condition. The complete equivalence is proved between modified Wightman axioms for relativistic theory and modified Osterwalder–Schrader axioms for Euclidean ...

Schwartz kernel theorem for the Fourier hyperfunctions

open access: yesTsukuba Journal of Mathematics, 1995
The purpose of this paper is to give a direct proof of the Schwartz kernel theorem for the Fourier hyperfunctions. The Schwartz kernel theorem for the Fourier hyperfunctions means that with every Fourier hyperfunction \(K\) in \({\mathcal F}(\mathbb{R}^{n_1}\times \mathbb{R}^{n_2})\) we can associate a linear map \[ {\mathcal K}:{\mathcal F}(\mathbb{R}^

초함수공간에서의 상미분방정식의 연구와 직교다항식에의 응용 [PDF]

open access: yes, 1991
학위논문(박사) - 한국과학기술원 : 수학과, 1991.8, [ [ii], 57 p. ]As a kind of generalized functions, hyperfunctions are, in some sense, more naturally adapted to the study of partial differential equations than L. Schwartz``s distributions.

Asymptotische Hyperfunktionen, temperierte Hyperfunktionen und asymptotische Entwicklungen [PDF]

open access: yes, 2005
Wir führen eine neue Unterklasse der Fourier Hyperfunktionen mit polynomialen Wachstumsbedingungen ein mit dem Ziel, asymptotische Entwicklungen von Hyperfunktionen studieren zu wollen, wie sie für gewisse Distributionenklassen bekannt sind.

Fourier transformation of Sato's hyperfunctions

open access: yesAdvances in Mathematics, 2005
A new generalized function space in which all Gelfand-Shilov classes $S^{\prime 0}_α$ ($α>1$) of analytic functionals are embedded is introduced. This space of {\it ultrafunctionals} does not possess a natural nontrivial topology and cannot be obtained via duality from any test function space.

DENSENESS OF TEST FUNCTIONS IN THE SPACE OF EXTENDED FOURIER HYPERFUNCTIONS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2004
Let \(F_{(h,\nu)}\) be the space of differentiable functions \(\varphi(x)\) for which some sup-norm is finite. Then one has the continuous embedding \(F_{(h,\nu)}\subset F_{(h',\nu')}\), \(h\geq h'>0, \nu\geq\nu'\). Let \(\mathcal G=\bigcap_{h,\nu}F_{(h,\nu)}\) be endowed with the natural projective topology.

Support and kernel theorem for Fourier hyperfunctions

open access: yesOsaka Journal of Mathematics, 2001
The existence and the characterization of the support of a Fourier hyperfunction \(u\) is not trivial; the support can contain or consists of infinite points. By definition, if \(u\) is a Fourier hyperfunction \((u\in Q' (\mathbb{D}^n)\), \(\mathbb{D}^n= \mathbb{R}^n\cup S^{n-1})\) and if it can be identified by an element of \(Q'(K)\), where \(K\) is ...
