Repulsion or attraction of critical points of isotropic Gaussian fields.

We study the local behaviour of critical points of smooth Gaussian stationary and isotrope fields$R^N \to R$ . In dimension 1 ($N=1$) we deduce from well known results of the literature that there is always repulsion between critical points: they are better spread than a Poisson process. In higher dimension, depending on the dimension, we observe some neutrality when $N=2$ and attraction for $N>2$. Specifying the index of the critical points we give some interpretation. Our results generalise the result by Beliaev et al that concern the random plane wave.
