摘要: Abstract We derive a result on the limit of certain sequences principal eigenvalues associated with some elliptic eigenvalue problems. This is then used to give complete description global structure curves positive steady states parameter dependent diffusive version classical logistic equation. In particular, we characterize bifurcation values from infinity states. The stability as well asymptotic behaviour solutions also discussed.
