Abstract: | Given two maps h : X ×K ? mathbbR{h : X times K rightarrow mathbb{R}} and g : X → K such that, for all x ? X, h(x, g(x)) = 0{x in X, h(x, g(x)) = 0} , we consider the equilibrium problem of finding [(x)tilde] ? X{tilde{x} in X} such that h([(x)tilde], g(x)) 3 0{h(tilde{x}, g(x)) geq 0} for every x ? X{x in X} . This question is related to a coincidence problem. |
