Construction of special solutions for nonintegrable dynamical systems with the help of the Painleve analysis
Abstract:
The generalized Henon-Heiles system has been considered. In two nonintegrable
cases with the help of the Painleve test new special solutions have been
found as Laurent series, depending on three parameters. One of parameters
determines a location of the singularity point, other parameters determine
coefficients of series. For some values of these parameters the obtained
Laurent series coincide with the Laurent series of the known exact solutions.
The Painleve analysis assists to find
solutions in the analytical form as well. For the Henon-Heiles system
new two-parameter solutions have been found in terms of the Jacobi elliptic
functions.
