%0 Journal Article %T Nonsmooth and nonlocal differential equations in lattice-ordered Banach spaces %A Carl Siegfried %A Heikkil£¿ S %J Boundary Value Problems %D 2005 %I Springer %X We derive existence results for initial and boundary value problems in lattice-ordered Banach spaces. The considered problems can be singular, functional, discontinuous, and nonlocal. Concrete examples are also solved. %U http://www.boundaryvalueproblems.com/content/2005/505679
