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