Abstract

Let Z_t be a one-dimensional symmetric stable process of order α with α∈(0,2) and consider the stochastic differential equation dX_t=φ(X_t-)dZ_t. For β<(1/α) ∧1, we show there exists a function φ that is bounded above and below by positive constants and which is Hölder continuous of order β but for which pathwise uniqueness of the stochastic differential equation does not hold. This result is sharp.
