ON THE VALIDITY OF A MODEL FOR THE REVERSALS OF THE EARTHS MAGNETIC-FIELD

We have used techniques of nonlinear dynamics to compare a special mod el for the reversals of the Earth's magnetic field with the observatio nal data. Although this model is rather simple, there is no essential difference to the data by means of well-known characteristics, such as correlation function and probability distribution. Applying methods o f symbolic dynamics we have found that the considered model is not abl e to describe the dynamical properties of the observed process. These significant differences are expressed by algorithmic complexity and Re nyi information.
