Fractal Dimensions and Scaling Laws in the Interstellar Medium: a new Field Theory approach
H. J. de Vega, N. S'anchez, F. Combes
We develop a field theoretical approach to the cold interstellar medium (ISM). We show that a non-relativistic self-gravitating gas in thermal equilibrium with variable number of a…
The General Solution of the 2-D Sigma Model Stringy Black Hole and the Massless Complex Sine-Gordon Model
H. J. de Vega, J. Ramírez Mittelbrunn, M. Ramón Medrano +1
The exact general solution for a sigma model having the stringy black hole (SBH) as internal manifold is found in closed form. We also give the exact solution for the massles…
Multi-String Solutions by Soliton Methods in De Sitter Spacetime
F. Combes, H. J. de Vega, A. V. Mikhailov +1
{\bf Exact} solutions of the string equations of motion and constraints are {\bf systematically} constructed in de Sitter spacetime using the dressing method of soliton theory. The…
