Abstract
A condition on the eigenvalues of two Gaussian processes is given that is sufficient for the boundedness of the difference of their\varepsilon-entropies. It is also proved that the difference between the\varepsilon-entropies of two strongly equivalent Gaussian processes is bounded. The relation between the\varepsilon-entropies of equivalent (or strongly equivalent) Gaussian processes is used for obtaining the asymptotic behavior (as\varepsilongoes to zero) of the\varepsilon-entropy of certain processes.
