Book Description

The trajectory of fractional calculus has undergone several periods of intensive development, both in pure and applied sciences. During the last few decades fractional calculus has also been associated with the power law effects and its various applications.

It is a natural to ask if fractional calculus, as a nonlocal calculus, can produce new results within the well-established field of Lie symmetries and their applications.

In Lie Symmetry Analysis of Fractional Differential Equations the authors try to answer this vital question by analyzing different aspects of fractional Lie symmetries and related conservation laws. Finding the exact solutions of a given fractional partial differential equation is not an easy task, but is one that the authors seek to grapple with here. The book also includes generalization of Lie symmetries for fractional integro differential equations.


  • Provides a solid basis for understanding fractional calculus, before going on to explore in detail Lie Symmetries and their applications
  • Useful for PhD and postdoc graduates, as well as for all mathematicians and applied researchers who use the powerful concept of Lie symmetries
  • Filled with various examples to aid understanding of the topics

"Lie symmetry analysis (or the Lie Method) has been extensively used for decades in the pursuit of finding exact solutions to partial differential equations. Yet, the Lie symmetry classification continues to receive a lot of attention in the field. Although not thoroughly pursued until more recently, fractional calculus may prove useful in the study of fractional differential equations. In this text, authors Hashemi (Univ. of Bonab, Iran) and Baleanu (Institute of Space Sciences, Romania) ask if there can be "conservation laws for fractional differential equations associated to real-world models?" They approach this question by analyzing fractional Lie symmetries, both classical and nonclassical, bringing the analysis to fractional partial differential equations and related self-adjointness and conservation laws. After a brief introduction to Lie symmetry analysis as applied to the integer-ordered Fornberg-Whitham and Black-Scholes equations, the authors investigate numerous fractional differential equations including the diffusion, Burger's, Airy's, and the gas dynamic equations. Once these are analyzed using nonclassical Lie symmetry analysis, the remainder of the text focuses on conservation laws and self-adjointness of fractional differential equations. [. . .] the volume of information provided in its scant 200 pages will certainly be useful to those interested in Lie symmetry analysis."
