Two fluid acoustic modes and inhomogeneous cosmologies
(IOP Publishing Ltd, 1993-12-01)
The weak discontinuities that can propagate in a relativistic two fluid system are examined and expressions obtained for their speed of propagation. The acoustic speeds and discontinuity amplitudes are described by their ...
Non-existence of renormalizable self-interaction in N = 2 supersymmetry for scalar hypermultiplets
(Elsevier, 1984-07-23)
We prove that the assumption of invariance under "isospin rotations", i.e. automorphisms of N = 2 supersymmetric charges, implies that there is no local renormalizable interaction among scalar hypermultiplets.
Existence of infinitely-many smooth, static, global solutions of the Einstein/Yang-Mills equations
(Springer-Verlag, 1993-01)
We prove the existence of infinitely-many globally defined singularity-free solutions, to the EYM equations with SU (2) gauge group. The solutions are indexed by a coupling constant, have distinct winding numbers, and their ...
Three‐Dimensional Motion of a Liquid Film Induced by Surface‐Tension Variation or Gravity
(The American Institute of Physics, 1969-10)
Steady flows of a thin layer of viscous liquid on a horizontal plane induced by the nonuniformity of surface tension at its free surface are treated. If the film is very thin, surface‐tension effects dominate gravity ...
Fractal chemical kinetics: Reacting random walkers
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-09)
Computer simulations on binary reactions of random walkers ( A + A → A ) on fractal spaces bear out a recent conjecture: ( ρ −1 − ρ 0 −1 ) ∞ t f , where ρ is the instantaneous walker density and ρ 0 the initial one, and f ...
Electron Relaxation and Molecular Vibrations: Triatomic Systems of the First‐Row Elements, the Methyl Radical, and Diazomethane and Ketene
(The American Institute of Physics, 1970-03-15)
The well‐known second‐order perturbation method is used to correlate the bond–bond interaction constants in ground and excited electronic states of triatomic systems of the first‐row elements, and unusual force constants ...
Studying artificial life with cellular automata
(Elsevier, 1986)
Biochemistry studies the way in which life emerges from the interaction of inanimate molecules. In this paper we look into the possibility that life could emerge from the interaction of inanimate artificial molecules. ...
The long time behavior of a finite amplitude shear Alfven wave in a warm plasma
(IOP Publishing Ltd, 1976-10-01)
The long time behavior of a monochromatic, finite amplitude shear Alfven wave is studied by means of the Krylov-Bogoliubov-Mitropolsky perturbation technique. The plasma model is assumed to be described by the linearly ...
