Functional determinants in the presence of zero modes
Klaus Kirsten, Alan J. McKane
We present a simple and accessible method which uses contour integration methods to derive formulae for functional determinants. To make the presentation as clear as possible we il…
A New Spectral Cancellation in Quantum Gravity
Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1
A general method exists for studying Abelian and non-Abelian gauge theories, as well as Euclidean quantum gravity, at one-loop level on manifolds with boundary. In the latter case,…
Heat content asymptotics for spectral boundary conditions
Peter Gilkey, Klaus Kirsten, JeongHyeong Park
We study the short time heat content asymptotics for spectral boundary conditions. The heat content coefficients are shown to be non-local and some preliminary results concerning t…
Heat trace asymptotics defined by transfer boundary conditions
Peter Gilkey, Klaus Kirsten, Dmitri Vassilevich
We compute the first 5 terms in the short-time heat trace asymptotics expansion for an operator of Laplace type with transfer boundary conditions using the functorial properties of…
On properties of the asymptotic expansion of the heat trace for the N/D problem
Stuart Dowker, Peter Gilkey, Klaus Kirsten
The spectral problem where the field satisfies Dirichlet conditions on one part of the boundary of the relevant domain and Neumann on the remainder is discussed. It is shown that t…
Casimir Energy in Non-Covariant Gauges
Giampiero Esposito, Alexander Yu. Kamenshchik, Klaus Kirsten
The zero-point energy of a conducting spherical shell is studied by imposing the axial gauge via path-integral methods, with boundary conditions on the electromagnetic potential an…
