[en] We study the Fourier transform for distributional sections of vector bundles over symmetric spaces of non-compact type. We show how this can be used for questions of solvability of systems of invariant differential equations in analogy to Hörmander’s proof of the Ehrenpreis-Malgrange theorem. We get complete solvability for the hyperbolic plane H2 and partial results for finite products H2 × · · · × H2 and the hyperbolic 3-space H3.
[lb] Mir studéieren Fourier Transformatioun fir Distributiounal Sektiounen vu Vektorbündelen u symmetresch Réim vun engem net-kompakten Typ. Mir bewéisen wéi et fir d’Léisbarkeet vu Systémer vun invarianten Differentialequatiounen an Analogie zu Hörmander’s Schätzungen, ugewand ka ginn. Mir kréien komplett Léisbarkeet fir hyperbolesch Pléng H2 a partial Résultater fir Produkter H2 ×· · ·×H2, wéi och fir hyperbolesch 3-Réim H3.
