摘    要：In this talk, we establish necessary and sufficient conditions for various of functional inequalities of onedimensional stable jump diffusions. Combined with the authors’ previous findings, these results collectively construct a stability diagram analogous to that of one-dimensional diffusion processes and birth-death processes. The tools we employ include the variational formula for Dirichlet eigenvalues, the construction and estimation of harmonic functions and killed Green functions, the fractional Hardy inequality, and the construction of Lyapunov function sequences. Finally, we will also discuss the feasibility of this problem for general symmetric L´evy processes and explore functional inequalities from the perspective of capacity.
