comment Interchange differential operator with Lebesgue integral.
@fgp A reference is an answer. Getting downvoted and being received negatively after taking the effort and time to write a reference for a result I know where to find (and for which I do not wish to re-transcribe the theorems in the reference) just makes want to stop answering such questions in the future.

comment Product of stationary stochastic process
@phil12 It is not a good idea to ask two questions in one post. Anyway as hint, write $f_z$ as a function of $\gamma_z$, replace $\gamma_z$ by the product found in the first question, apply the inverse transform to $\gamma_x$, interchange summation and integration (after justifying why you could do it), apply the inverse transform to $\gamma_y$ and you've got your answer.

comment Sum of stationary process
Which stationarity concept are you using? Strict stationarity, covariance stationarity etc...?
