Stochastic Modelling of Non-stationary Smooth Phenomena,cular care is taken in order to prove that the condition of positive definiteness of the covariance function is satisfied. The estimate of the covariance function is afterwards obtained by means of local estimates. The method has been tested on a set of simulated data.

Nevertheless, even at a first glance, these data seem to show a correlation pattern: for instance, we can have all sinking benchmarks along a control leveling line. In these cases it seems reasonable to make the

Generally, with the standard methods on the sphere, we reach a good fitting only up to the first zero of the empirical function. In this work we have investigated how much the collocation filtering is affected by a poor fitting of the empiric

Previously scattered over numerous di?erent publications, the results are presented from the viewpoint that the Hamilton map and the geometry of bicharacteristics completely characterizes the well/ill-posedness of the Cauchy pr
