= Reproducing-kernel Hilbert space of a stationary Gaussian process
{c}

If a stationary <Gaussian process> has covariance spectral density $\widehat K$, its reproducing-kernel Hilbert space has norm
$$
\lVert f\rVert_{\mathcal H_K}^2
=c\int\frac{|\widehat f(u)|^2}{\widehat K(u)}\,du
$$
on the functions for which this integral is finite.
