WebWe describe it in terms of a simple data structure, which we call the Corner Table. It represents the connectivity of any manifold mesh as two tables, V and O, such that for a corner c, which is the association of a triangle with a vertex, V [c] is an integer reference to the vertex of c and O [c] is an integer reference to the opposite corner. WebWhen an additional chiral symmetry is present, $\frac{e}{2}$ corner charges are accompanied by zero-energy corner-localized states. We show the application of our indices in a number of atomic and fragile topological insulators and discuss the role of fractional charges bound to disclinations as bulk probes for these crystalline phases.
