文摘We study positive solutions to the following higher order SchrSdinger system with Dirichlet boundary conditions on a half space: where a is any even number between 0 and n. This PDE system is closely related to the integral system where G is the corresponding Green's function on the half space. More precisely, we show that every solution to (0.2) satisfies (0.1), and we believe that the converse is also true. We establish a Liouville type theorem the non-existence of positive solutions to (0.2) under a very weak condition that u and v are only locally integrable.
