The publication of the rst edition of the book "Lagrangian and Hamiltonian Dynamics" gives me tremendous joy. This book was specically developed to adhere to the most recent and changed syllabus created for UG and PG students. An adequate depth of coverage with a respectable breadth has been attempted. A signicant number of problems are present in the book. If a student follows through with all of these, we hope that he or she will understand and like the topic.

Special functions are mathematical functions that have established names and notations due to their importance in mathematical analysis, functional analysis, geometry, physics, or other applications. This short text gives clear descriptions and explanations of the Gamma function, the Probability Integral and its related functions, Spherical Harmonics Theory, The Bessel function, Hermite polynomials and Laguerre polynomials. Each chapter finishes with a description of how the function is most commonly applied and a set of examples for the student to work through.

A tensor is an entity which is represented in any coordinate system by an array of numbers called its components. The components change from coordinate system to coordinate in a systematic way described by rules. The arrays of numbers are not the tensor; they are only the representation of the tensor in a particular coordinate system.
