In this thesis we apply the Malliavin calculus in order to obtain the local asymptotic normality (LAN) property from discrete observations for certain uniformly elliptic diffusion processes with jumps. In Chapter 2 we review the proof of the local asymptotic mixed normality (LAMN) property for diffusion processes with jumps from continuous observations, and as a consequence, we derive the LAN property when supposing the ergodicity of the process. In Chapter 3 we establish the LAN property for a simple Lévy process whose drift and diffusion parameters as well as its intensity are unknown. In Chapter 4, using techniques of the Malliavin calculus and the estimates of the transition density, we prove that the LAN property is satisfied for a jum...
