Abstract
The object of investigation in this paper is a nonlinear ordinary differential equation obtained by means of selfsimilar reduction of the generalized Burgers equation $u_t+u^\beta u_x+\lambda u^\alpha=\delta u_{xx}$ with the nonlinear damping term $\lambda u^\alpha$. More exactly, the authors study the initial value problem $g"+2\eta g'+2\beta^{1}g2^{3/2}g^\beta g'4\lambda g^\alpha=0$, $g(0)=\nu$, $g'(0)=0$ by using both numerical and analytical methods. Here $\alpha>0$, $\beta=(\alpha1)/2>0$, $\lambda$, $\delta>0$ and $\nu >0$ are constants. Existence of positive bounded solutions with exponential and algebraic types of decay to zero at infinity is proved for special ranges of parameters.
