We give a brief introduction to nonlinear equations with fractional Laplacian and present some recent work on the study of nonnegative solutions to nonlinear equations with fractional Laplacian. We focus on Bocher type theorems. These Bocher type theorems are used to derive maximum principles on a punctured ball. We also plan to provide some applications.
