摘要：

In this work we obtain a Liouville theorem for positive, bounded solutions of the equation (Delta)(s) u = h (x (N)) f (u) in R-N where (-Delta)(s) stands for the fractional Laplacian with s is an element of (0; 1), and the functions h and f are nondecreasing. The main feature is that the function h changes sign in R, therefore the problem is sometimes termed as indefinite. As an application we obtain a priori bounds for positive solutions of some boundary value problems, which give existence of such solutions by means of bifurcation methods.
