The calculation is offerred as a particular application of a general technique developed earlier for obtaining heat-kernel coefficients on a bounded generalised cone which involves writing the sphere and ball \zfs, and coefficients, in terms of Barnes \zfs\ and generalised Bernoulli polynomials. Functional determinants are computed. Spinors are also treated by the general method.34 pages, JyTeXHigh Energy Physics - Theorytext
