This paper investigates the existence and asymptotic behavior of solutions for weighted p(t)-Laplacian system multipoint boundary value problems in half line. When the nonlinearity term f(t,,) satisfies sub-(p--1) growth condition or general growth condition, we give the existence of solutions via Leray-Schauder degree.
