  • Asymptotic Methods for some third order Nonlinear Differential Equations 
    Alam, Md. Shamsul (University of Rajshahi, 1995)
    In this thesis, we investigate the oscillations of third order nonlinear systems by the asymptotic method. The asymptotic method of Krylov-Bogoliubov-Mitropolskii (KBM) is a popular technigue for obtaining analytic solution ...
  • KBM Asymptotic Method for third order Nonlinear Oscillations 
    Alam, Md. Shamsul (University of Rajshahi, 2000)
    In most treatments or nonlinear oscillations hy perturbation method. only periodic oscillations are treated; transients are not considered. Krylov and Bogoliubov have used a perturbation method to discuss transients in the ...
