Abstract:
ITo better understand the existence and behavior of the solution to the following fractional equations

where

,

is the fractional Laplacian operator,

is a region with a smooth boundary (which can be a full space)

and satisfy some certain conditions. In this paper, we will prove a correspondence between the solutions of the above system and the solutions of a particular fractional equation, which, combining the non-existence, existence, and uniqueness of the solutions of a particular fractional equation, can give out the non-existence, existence and uniqueness of the solutions of the above system.
