Tachyon Condensates and String Theoretic Inflation
Eric Raiten
Cosmological solutions of the beta function equations for the background fields of the closed bosonic string are investigated at the one-loop level. Following recent work of Kostel…
Exact Path Integrals by Equivariant Cohomology
Hans Dykstra, Joe Lykken, Eric Raiten
It is a common belief among field theorists that path integrals can be computed exactly only in a limited number of special cases, and that most of these cases are already known. H…
All Or Nothing: On the Small Fluctuations of Two-Dimensional String-Theoretic Black Holes
Gerald Gilbert, Eric Raiten
A comprehensive analysis of small fluctuations about two-dimensional string-theoretic and string-inspired black holes is presented. It is shown with specific examples that two-dime…
Asymptotic Behavior of 2-d Black Holes
E. Raiten
We consider the solutions of the field equations for the large dilaton gravity model in dimensions recently proposed by Callan, Giddings, Harvey and Strominger (CGHS). We…
Perturbations of a Stringy Black Hole
E. Raiten
We extend the three dimensional stringy black hole of Horne and Horowitz to four dimensions. After a brief discussion of the global properties of the metric, we discuss the stabili…
