Mathematical physics is an interdisciplinary science of physics and mathematics that is concerned with the formulation of mathematical models and their application to solve problems in physics. Mathematical models such as Lagrangian and Hamiltonian formulations have applications in classical mechanics. The field also uses partial differential equations, quantum theory, statistical mechanics and relativity to solve complex problems. This book is a compilation of topics that discuss the most relevant methods and principles of mathematics that are applied to the solution of physical problems. It further comprises of researches done by experts across the globe to advance the theoretical and applied aspects of mathematical physics. This book is aimed at physicists, mathematicians and students in this domain.
