In this work, we present a new concept of measure-ergodic process to define
the space of measure pseudo almost periodic process in the p-th mean sense.
We show some results regarding the completeness, the composition theorems
and the invariance of the space consisting in measure pseudo almost periodic
process. Motivated by above mentioned results, the Banach fixed point
theorem and the stochastic analysis techniques, we prove the existence,
uniqueness and the global exponential stability of doubly measure pseudo
almost periodic mild solution for a class of nonlinear delayed stochastic
evolution equations driven by Brownian motion in a separable real Hilbert
space. We provide an example to illustrate the effectiveness of our results.
