Brief Description
Fractals and Chaos Theory has not only laid a dramatic impact on mathematics, but also finds vivid applications in various streams of geosciences. The session is open for all the papers, which are based on fundamental concepts of fractal geometry and chaotic dynamics and their applications in geosciences, including related concepts like multifractals and wavelets. Various aspects of non-linear dynamical systems can be related to fractal processes in context of geological and geophysical problems. The session covers broad range of the geo-processes that obey power law like earthquake processes, potential field, flow problems etc including new trends and advancements in the techniques to characterize earth’s non-linear dynamics.

We focus on the application of fractals and other non-linear computational method to cater among the geophysicists working on different aspects of geophysical inversion, modeling, and data analysis. The session will leap through from fundamental theoretical research to applied research in non-linear processes, viz. fractals, chaos, self-organized criticality, aftershock sequence analysis of earthquakes with main focus on analysis of geophysical data using non-linear methods. It is well known that all geophysical data generally shows non-linear characteristics, viz. the after shock sequence of earthquake events, physical properties of the Earth, viz. density, susceptibility, conductivity etc. Hence there is need to understand their non-linear behavior and reformulate the analysis of these data sets for better and precise results. Significant research has been done for behavioral understanding of few physical parameters, but it is yet inadequate. We aim to address these challenging frontier problems hearing the views and ideas of leading workers in this field at Singapore. Contributions from all these fields are solicited. Papers presented in this session are likely to be published in some standard journal.
