Lens space determinants

More analysis of operator determinants on homogeneous three dimensional lens spaces is presented with the emphasis on numerics so that Laplacians for massive fields can be dealt with. Polyhedral quotients are also briefly considered. Twisted fields, corresponding to flat connections, are looked at and examples of determinants computed. Twisted cyclic quantities are sufficient to determine those for any twisting on any factor. An application to the thermodynamics on sphere quotients is given. Some computations are made for inhomogeneous lens spaces and higher dimensions are commented on. Minimal coupling is also dealt with.
