Two-Parametric Quantum-Deformed Dual Amplitude
From a 2-parametric deformation of the harmonic oscillator algebra we
construct a 4-point dual amplitude with nonlinear trajectories. The earlier
versions of the q-deformed dual models are reproduced as limiting cases of the
present model.Comment: 10 p. (LaTex), ITP-94-29E (misprints are corrected
Stability analysis of some integrable Euler equations for SO(n)
A family of special cases of the integrable Euler equations on
introduced by Manakov in 1976 is considered. The equilibrium points are found
and their stability is studied. Heteroclinic orbits are constructed that
connect unstable equilibria and are given by the orbits of certain 1-parameter
subgroups of SO(n). The results are complete in the case and incomplete
for .Comment: 15 pages, LaTeX, minor stylistic changes in v
