The vacuum energy for a massless scalar field defined on a hyperbolic manifold H3/Γ is evaluated using zeta‐function and heat kernel regularization techniques and Selberg trace formula for cocompact group Γ. A negative contribution to the vacuum energy associated with trivial line bundle related to character χ=1 is found.

Abstract
The vacuum energy for a massless scalar field defined on a hyperbolic manifold H3/Γ is evaluated using zeta‐function and heat kernel regularization techniques and Selberg trace formula for cocompact group Γ. A negative contribution to the vacuum energy associated with trivial line bundle related to character χ=1 is found.File in questo prodotto:
