Abstract
Renz (1996), El Machkouri and Ouchti (2007) and Mourrat (2013) have established some tight bounds on the rate of convergence in the Central Limit Theorem for martingales. In the present talk, we present some exact rates of convergence in the central limit theorem for martingales with differences having conditional moments of order 2+ρ, ρ>0. Our results generalise and strengthen the bounds mentioned above.
