Critical and umbilical points of a non-Gaussian random field
Critical and umbilical points of a non-Gaussian random field
Random fields in nature often have, to a good approximation, Gaussian characteristics. For such fields, the number of maxima and minima are the same. Furthermore, the relative densities of umbilical points, topological defects which can be classified into three types, have certain fixed values. Phenomena described by nonlinear laws can, …
