Stochastic differential equations driven by stable processes for which pathwise uniqueness fails
(North-Holland (Elsevier), 2004-05)
Let Z [subscript] t be a one-dimensional symmetric stable process of order [alpha] with [alpha is an element of the set] (0, 2) and consider the stochastic differential equation
dX [subscript] t = [omega] (X [subscript] t−)dZ [subscript]t.
For [beta] < 1 [divided by alpha] ^ 1, we show there exists a function that is ...
Uniqueness for reflecting Brownian motion in lip domains
(Elsevier, 2005-03)
A lip domain is a Lipschitz domain where the Lipschitz constant is strictly less than one. We prove strong existence and pathwise uniqueness for the solution X = {X [subscript] t, t [is less than or equal to] 0} to the Skorokhod equation dX [subscript] t = dW [subscript] t + n(X [subscript] t)dL [subscript] t, in planar lip ...
