Introduction,ph theory is another powerful area for the obvious reason that it is used to study the microscopic structure of a crystal (and any molecule) as a 3D (three-dimensional) ., in which each atom (or each cluster of atoms) is represented by a vertex of the net, and each edge of the net represents a . (or a polymeric ligand) in the crystal structure.

Covering Graphsa covering map from the line . onto the circle .., which somehow suggests an idea why we use the term “covering”. The canonical projection ., introduced in Example 2.5, is another example of a covering map.
