Effect of noises on the stochastic basin of attraction.
(a) The closed set K with noise intensities σ = ε = 0.5, exit domain B(x−) = (0, 1.48971). (b) The stochastic basin of attraction in the model with Brownian motion, return to K from domain D = (0, 0.4387)∪(0.9869, 6). (c) Same as (b) except in the model under α-stable Lévy motion, with α = 0.5. (d) Same as (c) except α = 1.5.
