THE BIFURCATION OF STEADY STATE AND STABILITYOF A MUTUALISTIC SYSTEM
一类互惠共存系统的定态分歧与稳定性

In this paper a mutualistic system is investigated. The bifurcation of the non..negative stationary solutions and its asymptotic stability are discussed by spectral analysis,the simple eigenvalues bifurcation theorem and the Liapunov-Schmidt procedure.Moreover, the ranges of parameters are found for which there exist nontrivial andstable steady-state solutions.
