| dc.description.abstract | We consider the stochastically perturbed cubic difference equation with variable coefficients xn+1=xn(1−hnx2n)+ρn+1ξn+1,n∈N,x0∈R. Here (ξn)n∈N is a sequence of independent random variables, and (ρn)n∈N and (hn)n∈N are sequences of nonnegative real numbers. We can stop the sequence (hn)n∈N after some random time N so it becomes a constant sequence, where the common value is an FN -measurable random variable. We derive conditions on the sequences (hn)n∈N , (ρn)n∈N and (ξn)n∈N , which guarantee that limn→∞xn exists almost surely (a.s.), and that the limit is equal to zero a.s. for any initial value x0∈R . | en |
