P-Funktionale und Randwerte zu Hypoelliptischen Differentialoperatoren

Abstract: Die Einfiihrung verallgemeinerter Funktionen ist ein wichtiges Hilfsmittel in der Theorie partieller Differentialgleichungen. So ist die Theorie der Distributionen (oder gewisser Teilrfi.ume der Distributionen) grundlegend fiJr eine umfassende Untersuchang der partiellen Differentialgleichungen mit konstanten Koeffizienten ([4, 14]). Eine noch gr63ere Klasse verallgemeinerter Funktionen, die ebenfalls zu vielf~iltigen neuen Ergebnissen gefiihrt hat, sind die 1959/60 yon H. Sato eingefiJhrten Hyperfunktionen ([… Show more

“…When doing so we will profit a lot of Bengel's point of view of hyperfunctions (i.e. considering harmonic functionals instead of analytic functionals (see [2], [54] and also [35,36])). Moreover, we will constantly use the Grothendieck-Tillmann-duality of harmonic functionals and harmonic functions explained in the previous section (see Theorem 5.2).…”

“…Then both approaches are translated to the boundary value approach for harmonic (Section 6) and holomorphic functions (Section 7). We will profit a lot from Bengel's point of view, i.e., considering harmonic functionals instead of analytic functionals, which lead to a special case of P-functionals of Bengel (see [2], [54] and also [35]). We explain this identification in Section 5.…”

“…This research is continued by several authors like Bolley et al [1], Zanghirati [22][23][24] and Bouzar and Chaili [3]. Langenbruch utilized generalized Gevrey classes in connection with different problems, like boundary values of zero solutions of hypoelliptic differential operators [12,13], diametral dimension of solution spaces [14] and isomorphic classification [15].…”
