Uniqueness by random perturbation: The Leray-alpha model of Euler equation

We deal with the 3D inviscid Leray-\alpha model. The well posedness for this problem is not known; by adding
a random perturbation we prove that there exists a unique (in law) global solution.
The random forcing term formally preserves conservation of energy.
The result holds for initial velocity of finite energy and the solution has finite energy a.s..
These results continue to hold in the 2D case.
