On certain mapping properties of a weighted totally geodesic k-plane transform on the real hyperbolic space

Abstract

In this article, we study a weighted analogue of the totally geodesic k-plane transform on the real hyperbolic space. Throughout the article, we are concerned with the mapping properties of this transform. Particularly, we first consider the existence of the operator on weighted Lebesgue spaces, where the weights under consideration are natural to the geometry of the hyperbolic space. Then, we proceed to see the L^p-improving mapping properties of the said transform on radial functions. Further, we also prove end-point boundedness results on Lorentz spaces of radial functions. Lastly, we look into the problem of weighted L^p-L^p boundedness, and obtain partial results in this direction. In the way of obtaining these results, we also give a spherical integral representation of the weighted totally geodesic k-plane transform.
