Abstract
Let (Z t ) t⩾0 be a one-dimensional symmetric α-stable process with α ∈ (0, 2), and let σ be a bounded (from above and from below) and 1/(α ∨ 1)-Hölder continuous function on ℝ. Consider the stochastic differential equation dX t = σ(X t−)dZ t , which admits a unique strong solution. By using the splitting technique and the coupling method, we derive the Hölder continuity of the associated semigroup.
