Chapter I. Subdifferentiability and Duality Mappings

Abstract
Our aim in this Chapter is to introduce the notion of duality mapping on a Banach space X; to this purpose we survey basic results of convex analysis and connect them with the differentiability properties of the norm on X.

Chapter II. Characterizations of Some Classes of Banach Spaces by Duality Mappings

Abstract
In this chapter we shall characterize some classes of Banach spaces, among which strictly convex spaces, uniformly convex spaces and reflexive Banach spaces in terms of properties of the duality mapping such as continuity, injectivity or surjectivity. Some applications to Lp and 1p spaces are given.

Chapter III. Renorming of Banach Spaces

Abstract
This chapter is mainly concerned with the basic renorming theorems: the renorminy of c0(Γ) and the theorems of Lindenstrauss and Trojanski. Moreover Aspund’s averaging techinque is presented.

Chapter IV. On the Topological Degree in Finite and Infinite Dimensions

Abstract
We give a short (analytical) presentation of Brouwer’s theory of the topological degree of continuous mappings in finite dimensional Banach spaces and a generalization of it to A proper mappings in Banach spaces. The connection with the Leray-Schauder degree is commented and some applications to the topological degree of normalized duality mappings are made.

Chapter V. Nonlinear Monotone Mappings

Abstract
In this chapter we shall present various results on nonlinear monotone mappings in Banach spaces, pointing out further properties of duality mappings. Applications are made to some nonlinear functional equations.

Chapter VI. Accretive Mappings and Semigroups of Nonlinear Contractions

Abstract
In this chapter we first present general result on accretive mappings on a Banach space X in order to tackle then the problem of the genration of semigroups of nonlinear contractions.
