| Abstract: | Fixed points of condensing operator are studied by using topological degree theory. Un- der the certain boundary conditions, we get existence of fixed points for the nonlinear operator, the~e conclusions improve or generalize some recent results in known literature. |

| Keywords: | condensing operator topological degree homotopy invariance fixed point |
