报告摘要:

    This work focuses on a class of jump-diffusions with state-dependent switching. First, the existence and uniqueness of the solution are obtained by a successive construction method. Then, the Feller property is proved by means of introducing auxiliary processes and by making use of Randon-Nikodym derivatives. Furthermore,irreducibility and all compact sets being petite are demonstrated.
    Based on these results, the exponential ergodicity is established under a general Lyapunov condition. Finally, easily verifiable conditions for exponential ergodicity are established when the jump-diffusions with state-dependent switching are linearizable with respect to the state variable (the variable corresponding to the jump-diffusion component) in a neighborhood of the infinity, and some examples are presented for illustration.
