Fourier transformation of $$O(p,q)$$-invariant distributions. Fundamental solutions of ultra-hyperbolic operators. (English) Zbl 06684637
Summary: In this study, we present some formulae for the Fourier transform of $$O(p,q)$$-invariant temperate distributions. The formulae are used to calculate fundamental solutions of homogeneous and non-homogeneous ultra-hyperbolic operators.
