Symmetric Bouchaud’s model on Z2 is a Markov chain X(t) whose transition rates are given by wxy = ν exp(−βEx ) if x, y are neighbours in Z2 . We study the behaviour of two correlation functions: P[X(tw + t) = X(tw )] and P X(t ) = X(tw )∀t ∈ [tw , tw + t] . We prove the (sub)aging behaviour of these functions when β > 1.
