Smoothing of singular intersections of ellipsoids: pyramitoid
Abstract
The goal of this work is to continue the study the smoothings of 3-dimensional manifolds with singularities obtained as small covers of non simple right-angle Coxeter polyhedral orbifolds. They appear in the study of coaxial intersections of ellipsoids. In particular we introduce the concept of n-pyramitoid generalizing the n-pyramid.
