We consider the stochastic differential equation
(1) $du(t) = a(u(t),ξ(t))dt + ∫_{Θ} σ(u(t),θ) 𝓝_p(dt,dθ)$ for t ≥ 0
with the initial condition u(0) = x₀. We give sufficient conditions for the existence of an invariant measure for the semigroup ${P^t}_{t≥0}$ corresponding to (1). We show that the existence of an invariant measure for a Markov operator P corresponding to the change of measures from jump to jump implies the existence of an invariant measure for the semigroup ${P^t}_{t≥0}$ describing the evolution of measures along trajectories and vice versa.
