Localization of Equivariant Cohomology for Compact and Non-compact Group Actions
A. A. Bytsenko, M. Libine, F. L. Williams
We give a brief introduction to the Berline-Vergne localization formula for the finite-dimensional setting and indicate how the Duistermaat-Heckman formula is derived from it. We c…

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…
