Hyperbolic Space Forms and Orbifold Compactification in M-Theory
A. A. Bytsenko, M. E. X. Guimaraes, J. A. Helayel-Neto
We analyze solutions of string theory and supergravity which involve real hyperbolic spaces. Examples of string compactifications are given in terms of hyperbolic coset spaces of f…
Spectral Functions for Gauge Fields in Rindler-Like Spaces
A. A. Bytsenko, A. E. Goncalves, V. S. Mendes
A class of conformal deformations of Rindler-like spaces is analyzed. We study the spectral properties of the Laplace operators associated with forms and acting in these spaces…
Forms on vector bundles over compact hyperbolic manifolds and entropy bounds
A. A. Bytsenko, V. S. Mendes, A. C. Tort
We analyze gauge theories based on abelian forms in real compact hyperbolic manifolds. The explicit thermodynamic functions associated with skew--symmetric tensor fields are ob…
Thermodynamic Properties of the Relativistic Composite String - Expository Remarks
I. Brevik, A. A. Bytsenko, B. M. Pimentel
The Casimir energy for the transverse oscillations of a piecewise uniform closed string is calculated. The great adaptability of this string model with respect to various regulariz…
Casimir Energy and Thermodynamic Properties of the Relativistic Piecewise Uniform String
I. Brevik, A. A. Bytsenko
The Casimir energy for the transverse oscillations of a piecewise uniform closed string is calculated. The great adaptibility of this string model with respect to various regulariz…
