Abstract

The connection between topology and quantum mechanics is one of the cornerstones of modern physics. Several examples of current interest like the Aharonov-Bohm effect in quantum mechanics, monopoles and instantons in quantum field theory, the quantum Hall effect in condensed matter physics, anyons in topological quantum computation, and the AdS-CFT correspondence in string theory illustrate this connection. Since classical mechanics is a limiting case of quantum mechanics, it behooves us to ask how topology impacts classical mechanics. Topological considerations do play an important role in the classical context too, for example in fluid vortices and atmospheric dynamics. With a desire to understand this connection more deeply, we study classical mechanics on finite spaces. Towards this end, we use the formalism developed by Bering and identify the corrections to the Klein-Gordon equation due to the presence of the boundary. We solve the modified equation in various dimensions under suitable assumptions of symmetry.
