This thesis covers two topics. The first part studies the asymptotic behaviour of spherical super functions on non-compact symmetric super spaces of low rank. This plays an important role in the harmonic analysis of such spaces. It is described by Harish-Chandra’s c-function. The c-function is the first step in order to obtain an explicit series expansion of spherical super functions. This expansion allows to estimate the growth behaviour of these functions. The main difficulty in determining the c-function is that the necessary integration formulas generalise to the super case only for compactly supported integrands.
The second part focuses on the Fourier transform on the symmetric super space SOSp(1,1+p|2q)/SOSp(1+p|2q) to obtain a Fourier inversion formula. In distinction to the classical setting, the c-function might have zeros with positive real part in the super case. Therefore, the residues of 1/c lead to additional terms in the inversion formula. The proof of this formula makes it necessary to work with polar coordinates which in general produce boundary terms. For this purpose, this space will be identified with the Poincare super ball. On this space, a necessary polar integration formula can be derived easily.
