Abstract
Let \(\mathbb{X}\) be a Riemannian symmetric space of non-compact type. Then \(\mathbb{X}\) is isomorphic to G∕K, where G is a connected, real, semisimple Lie group, and K a maximal compact subgroup. Consider further the Oshima compactification \(\widetilde{\mathbb{X}}\) of \(\mathbb{X}\) [8], which is a simply connected, closed, real-analytic manifold carrying an analytic G-action. The orbital decomposition of \(\widetilde{\mathbb{X}}\) is of normal crossing type, and the open orbits are isomorphic to G∕K, the number of them being equal to 2l, where l denotes the rank of G∕K.
