the study of nonlinear dynamical systems nuclear fission using hurwitz criterion

In this paper, the nonlinear dynamic system of equations, a type of nuclear ssion reactor is solved analytically and numerically. considering that the direct solution of three-dimensional dynamical systems analysis and more in order to determine the stability and instability, in terms of algebraic systems is diffcult. using certain situations in mathematics called hurwitz criterion, necessary and sucient conditions for a stable dynamical system is determined and the parameters that most in uence the quality of the dynamic behavior of a nuclear ssion reactor have been determined.
