3 Nontrivial stationary solution
\
3.1 Spectral theory of integro-differential operator
The eigenvalue problem is an important tool to study the longtime behaviors of elliptic and parabolic problems, especially the sign of principal eigenvalue of the linearized operator can determine the existence and stability of nontrivial stationary solution, even the persistence of species, see [20, 32, 44, 45].
\ 
\ And some standard properties have shown in [32].

3.2 The existence, uniqueness and stability of nontrivial stationary solution
Firstly, we shall the strong maximal principle for the stationary problem.
\ 
\ 
\ Notice that (3.5) (or (3.6)) has only one trivial solution u = 0.In the following, we still only consider the details for (3.5).
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ 
\ Hence, we obtain a contradiction, and so the theorem holds.
\ 
\ In summary, the results about the existence/nonexistence, uniqueness of nontrivial solutions of (3.5) and the stability of nontrivial/trivial solution are as follows.
