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…

Heat asymptotics with spectral boundary conditions
Stuart Dowker, Peter Gilkey, Klaus Kirsten
Let be an operator of Dirac type on a compact Riemannian manifold with smooth boundary. We impose spectral boundary conditions and study the asymptotics of the heat trace of th…
