Necessary And Sufficient

The physical significance of parameterization schemes and their role in developing an understanding of complex systems is discussed, using examples taken from solid state physics. In particular, the importance of determining the necessary and sufficient set of hypotheses which defines a parameterization scheme is emphasized. A classification of parameterization schemes is developed in order to simplify this problem, and some general principles concerning the derivation and use of such schemes are formulated.

Abstract The physical significance of “earthquake quanta” is discussed in the perspective of a proposed concept “seismon.” It is pointed out that the physical significance of earthquake quanta may be understood in the way similar to that of phonon in solid-state physics. Using the statistical properties of the seismons, the property such that for large earthquakes the mean stress drop is approximately constant, while for small events the mean stress drop increases with the seismic moment, may be obtained, without detailed considerations of the failure criteria and the interaction between different earthquake quanta.
