Geometric Entropy and Curvature Coupling in Conical Spaces: ζ Function Approach

The local ζ−function approach is implemented to regularize the natural path integral definition of the geometric entropy in the large mass black hole Euclidean manifold. The case of a massless field coupled with the (off-shell) singular curvature is considered. It is proved that the geometric entropy is independent of the curvature coupling parameter ξ avoiding negative values obtained in other...

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

A Comment on the Geometric Entropy and Conical Space

It has been recently pointed out that a definition of the geometric entropy using the partition function in a conical space does not in general lead to a positive definite quantity. For a scalar field model with a non-minimal coupling we clarify the origin of the anomalous behavior from the viewpoint of the canonical formulation.

Entropy Numbers in Weighted Function Spaces and Applications

We intend to give a rather brief summary of recent investigations concerning entropy numbers in weighted function spaces. For the sake of brevity we will restrict ourselves to some special \model" cases. We will thus always refer to the original papers 3], 4] and 5] for details and generalizations. Most of the presented results have been obtained in a joint work with Prof. H. Triebel.
