<p>In our paper [2], we have classified simple regular polyhedral BP-complexes, which are polyhedral complexes satisfying certain natural conditions on their vertex structures. As an addendum of this classification, we prove that 2-skeletons of higher dimensional regular polytopes are simple regular polyhedral complexes, but not polyhedral BP-complexes. The proof is done by a detailed investigation of their vertex structures.</p>

The concept of ideal boundary of Hadamard monifolds was introduced by Eberlein and O'Neill [3] in 1973, which had marked a millestone is the study of the geometry of noncompact Reimannian manifolds. Since then, it has been utilized in various fields of research on Hadamard manifolds. ...
