Spherical Casimir energies and Dedekind sums

J S Dowker
2004 Classical and quantum gravity  
Casimir energies on space-times having general lens spaces as their spatial sections are shown to be given in terms of generalised Dedekind sums related to Zagier's. These are evaluated explicitly in certain cases as functions of the order of the lens space. An easily implemented recursion approach is used.
