Abstract

Stochastic problems play a huge role in many applications including biology, chemistry, physics, economics, finance, mechanics, and several areas. In this paper, we are concerned with the nonlocal stochastic-integral problem of the arbitrary (fractional) orders stochastic differential equation \[ \frac{dX(t)}{dt}=f_{1}(t,D^{\alpha} X(t))+f_{2}(t,B(t)), \ \ t\in(0,T], \qquad X(0)=X_0 +\int_0^Tf_3(s, D^{\beta} X(s)) dW(s), \] where \(B\) is any Brownian motion, \(W\) is a standard Brownian motion, and \(X_0\) is a second order random variable. The Hyers - Ulam stability of the problem will be studied. The existence of solution and its continuous dependence on the Brownian motion \(B\) will be proved. The three spatial cases Brownian bridge process, the Brownian motion with drift and the Brownian motion started at \(A\) will be considered.
