SPDEs with fractional noise in space with index \(H<1/2\)
In this article, we consider the stochastic wave and heat equations on \(\mathbb{R}\) with non-vanishing initial conditions, driven by a Gaussian noise which is white in time and behaves in space like a fractional Brownian motion of index \(H\), with \(1/4
