摘要
A nonlinear age-dependent population model,which allows for consideration of theeffects of crowding and resource limitation,is presented.The basic properties of solution,such asexistence,positivity,uniqueness,and ultimate behavior,are discussed.Also,the condition of stabilityand controll-ability of the nonlinear population system is obtained.
