摘要:
It is well known that, in the study of the dynamical properties of nonlinear evolution system with nonlocal operators, the sign of the principal eigenvalue of linearized system play an important role. However, in the case of variable coefficients, in order to obtain the existence of principal eigenvalue for the cooperative and irreducible system, very strong conditions must be attached to the coefficients. In this talk we concern with the cooperative and irreducible system. By constructing the monotonic upper and lower control systems, we obtain the generalized principal eigenvalue of the operator and show that this generalized principal eigenvalue plays the same role as the usual principal eigenvalue.
