Abstract
Using the lattice structure, we give some methods of computation of the topological degree for the operator which is quasi-additive on lattice. The operator AA is not assumed to be a cone mapping. As applications, the existence of nontrivial solutions for the nonlinear Sturm–Liouville problem is discussed.
