Abstract
In this paper, we will show that if the sectional curvature of a Hadamard manifold $M$ is pinched by two negative constants, then $M$-valued jump-diffusion process $\{X_t;0\leq t\lt e\}$ satisfying suitable conditions on the Lévy measure is irreducible, transient and conservative. In order to show such properties of paths, we need the upper and lower estimates of the radial part of the jump-diffusion process.
