Global attracting set, exponential decay and stability in distribution of neutral SPDEs driven by additive $$\alpha$$-stable processes. (English) Zbl 1354.60072
Summary: In this paper, we are concerned with a class of neutral stochastic partial differential equations driven by $$\alpha$$-stable processes. By combining some stochastic analysis techniques, tools from semigroup theory and delay integral inequalities, we identify the global attracting sets of the equations under investigation. Some sufficient conditions ensuring the exponential decay of mild solutions in the $$p$$-th moment to the stochastic systems are obtained. Subsequently, by employing a weak convergence approach, we try to establish some stability conditions in distribution of the segment processes of mild solutions to the stochastic systems under consideration. Last, an example is presented to illustrate our theory in the work.
