The book covers nonlinear physical problems and mathematical modeling, including molecular biology, genetics, neurosciences,
artificial intelligence with classical problems in mechanics and astronomy and physics. The chapters present nonlinear mathematical
modeling in life science and physics through nonlinear differential equations, nonlinear discrete equations and hybrid equations.
Such modeling can be effectively applied to the wide spectrum of nonlinear physical problems, including the KAM (Kolmogorov-Arnold-Moser
(KAM)) theory, singular differential equations, impulsive dichotomous linear systems, analytical bifurcation trees of periodic
motions, and almost or pseudo- almost periodic solutions in nonlinear dynamical systems.
