Martin 2012-12-19T13:40:57Z 2012-12-19T13:40:57Z <p>Hello, Let consider a pure jump process on the unitary group on the complex plane : the jumps $exp(i)$ arrive randomly according to a Poisson process ; the support is composed of $exp(ix)$ with $x\in \mathbb{N}$. Is it a counter-example or I forget something ?</p>
