In recent years, fractional differentiation has drawn increasing attention in the study of so-called "anomalous" social and physical behaviors, where scaling power law of fractional order appears universal as an empirical description of such complex phenomena. It is worth noting that the standard mathematical models of integer-order derivatives, including nonlinear models, do not work adequately in many cases where power law is clearly observed. To accurately reflect the non-local, frequency- and history-dependent properties of power law phenomena, some alternative modeling tools have to be introduced such as fractional calculus.

Research in fractional differentiation is inherently multi-disciplinary and its application across diverse disciplines such as physics, chemistry, biology, polymer, medicine, mechanics, finance, social sciences, notably control theory and signal and image processing. This is well reflected by the wide scope of the articles reported in literature. The purpose of this symposium in series is to provide the participants with a broad overview of the state of the art on fractional systems, leading to the cross-fertilization of new research on theoretical, experimental and computational fronts for potential uses of fractional differentiation in diverse applications.

The topics of this symposium include: Anomalous diffusion; Automatic Control; Biology; Continuous Time Random Walk; Electrical Engineering; Electronics; Electrochemistry; Electromagnetism; Finance and Economics; Earth Science; Fractional Filters; Biomedical Engineering; Fractional Phase-Locked Loops; Fluid Mechanics; Fractional Variational Principles; Fractional Transforms; Fractional Wavelet; Composite Drug Signals; History of Fractional Calculus; Image Processing; Mathematical methods; Mechanics; Physics; Quantum Mechanics; Robotics; Signal Processing; Singularities Analysis and Integral Representations for Fractional Differential Systems; Special Functions Related to Fractional Calculus; Thermal Engineering; Viscoelasticity; etc.

We expect that 200 or so participants from around the world will attend the FDA12. The Organization Committee would like to cordially invite you to attend this great event.

We are looking forward to meeting you at the FDA'2012 symposium, in Nanjing, China!
