For a Banach Space X Garcia-Falset introduced the coefficient R(X) and showed that if R(X) 〈 2 then X has a fixed point. In this paper, we define a mean non-expansive mapping T on X in the sense that ||Tx - TY...

In this note we first prove a fixed point theorem in H-spaces which unities and extends the corresponding results in [6] and [9]. Then, by applying the fixed point theorem, we prove an existence theorem of an equilib...

In this paper we shall consider the nonresonance Dirichlet boundary value problemwhere λ>0 is a parameter, p>0 is a constant. Intervals of A are determined to ensure the existence of a nonnegative solution of the bou...
