Concepts and Applications of Fractional Calculus - Gerald Paterson
Fractional calculus is a branch of mathematical analysis involved in the study of several different possibilities of defining real number powers or complex number powers of the differentiation operator, integration operator (D) and of the integration operator (J), and developing a calculus for such operators. It has several applications in multiple fields of engineering and science such as electromagnetics, viscoelasticity, fluid mechanics, electrochemistry, biological population models, optics,..
