The purpose of this thesis is to study the pricing of exotic options in exponential Lévy models. In the first chapter we define Lévy processes, and present their properties. In the second chapter we first recall results on the existence and regularity of density of Lévy processes. For the supremum process of a Lévy process, we give sufficient conditions for existence and regularity of its probability density function (theorems 2.17, 2.19 and 2.23). In the third chapter we study the errors between the supremum of a continuous Lévy process and its discrete version. In the first part of the chapter, we focus on the L1 error (theorems 3.4, 3.8 and 3.11) using a reformulation of Spitzer's identity for Lévy processes (Proposition 3.2). In the sec...
