static

gather all simplices that are deleted in a collapse

The deleted simplices are the intersection of the open star of the vertex and the closed star of the edge. This comes down to one vertex, three edges, and two faces if the edge is on the interior. On the boundary it is one vertex, two edges, and one face.
