Green functions and dimensional reduction of quantum fields on product manifolds
Z. Haba
We discuss Euclidean Green functions on product manifolds P=NxM. We show that if M is compact then the Euclidean field on P can be approximated by its zero mode which is a Euclidea…
Green functions and Euclidean fields near the bifurcate Killing horizon
Z. Haba
We approximate a Euclidean version of a D+1 dimensional manifold with a bifurcate Killing horizon by a product of a two-dimensional Rindler space and a D-1 dimensional manifold M.…
Quantum field theory with an interaction on the boundary
Z. Haba
We consider quantum theory of fields ϕdefined on a D dimensional manifold (bulk) with an interaction V(ϕ) concentrated on a d<D dimensional surface (brane). Such a quantum field th…
Quantum field theory on manifolds with a boundary
Z. Haba
We discuss quantum theory of fields ϕdefined on (d+1)-dimensional manifold {\cal M} with a boundary {\cal B}. The free action W_{0}(ϕ) which is a bilinear form in ϕdefines the Gaus…
Green functions and propagation of waves in strongly inhomogeneous media
Z. Haba
We show that Green functions of second-order differential operators with singular or unbounded coefficients can have an anomalous behaviour in comparison to the well-known properti…
Dimensional reduction of quantum fields on a brane
Z. Haba
If we restrict a quantum field defined on a regular D dimensional curved manifold to a d dimensional submanifold then the resulting field will still have the singularity of the ori…
