Continuity in a pathwise sense with respect to the coefficients of solutions of stochastic differential equations

AbstractFor stochastic differential equations (SDEs) of the form dX(t) = b(X)(t)) dt + σ (X(t))dW(t) where b and σ are Lipschitz continuous, it is shown that if we consider a fixed σ ϵ C5, bounded and with bounded derivatives, the random field of solutions is pathwise locally Lipschitz continuous with respect to b when the space of drift coefficients is the set of Lipschitz continuous functions of sublinear growth endowed with the sup-norm. Furthermore, it is shown that this result does not hold if we interchange the role of b and σ. However for SDEs where the coefficient vector fields commute suitably we show continuity with respect to the sup-norm on the coefficients and a number of their derivatives
