Thanks.

The choice of a WGN is essentially to make your life easier. As long as the stochastic process converges to equilibrium you are free to choose the source.
As a matter of fact, in some cases such as fermionic theories, you are actually forced to introduce different distributions (kernels).

Hi!
Interesting paper. One more illustration of duality Markovian-Hamiltonian. The consequence of linearity.

White Gaussian noise. Why?

Thanks.
Best regards.

That’s a pleasing paper, including the other two authors whom I know, unlike D.O. Kimigayo to Susanne, whatever it means.
