Quantum Chrono-Topology of Nuclear and Sub-Nuclear Reactions
C. Syros, C. Schulz-Mirbach
A quantum time topological space is developed and applied to solve some problems about quantum theory. It is disconnected and satifies specific separation axioms. The degree of dis…
Evidence for an outflow from the Seyfert galaxy NGC 4051
P. E. Christopoulou, A. J. Holloway, W. Steffen +6
New observations using narrow band imaging, long-slit spectroscopy and MERLIN observations of the nuclear region of the Seyfert galaxy NGC~4051 have been made. An edge brightened,…
Solitons of axion-dilaton gravity
I. Bakas
We use soliton techniques of the two-dimensional reduced beta-function equations to obtain non-trivial string backgrounds from flat space. These solutions are characterized by two…
Universal aspects of string propagation on curved backgrounds
I. Bakas, K. Sfetsos
String propagation on D-dimensional curved backgrounds with Lorentzian signature is formulated as a geometrical problem of embedding surfaces. When the spatial part of the backgrou…
Toda Fields of SO(3) Hyper-Kahler Metrics
I. Bakas, K. Sfetsos
We examine the Toda frame formulation of the SO(3)-invariant hyper-Kahler 4-metrics, namely Eguchi-Hanson, Taub-NUT and Atiyah-Hitchin. Our method exploits the presence of a rotati…
