This thesis addresses the study of two semilinear elliptic problems that arise in Riemannian Geometry. More precisely, we are interested in the prescription of certain geometric quantities on Riemannian manifolds with boundary under conformal changes of the metric, namely, the Gaussian and geodesic curvatures on a compact surface and its boundary, and the scalar and mean curvatures on a manifold of higher dimension. Most of the results available in the literature concern closed manifolds, whereas the boundary cases have been less considered. In that regard, we highlight that the presence of the boundary leads to a wider variety of phenomena, many of which nd no counterpart on the closed versions of these problems. In particular, t...
