"The book describes Maxwell's equations first in their integral, directly testable form, then moves on to their local formulation. The first two chapters cover all essential properties of Maxwell's equations, including their symmetries and their covariance in a modern notation. Chapter 3 is devoted to Maxwell theory as a classical field theory and to solutions of the wave equation. Chapter 4 deals with important applications of Maxwell theory. It includes topical subjects such as metamaterials with negative refraction index and solutions of Helmholtz' equation in paraxial approximation relevant for the description of laser beams.Chapter 5 describes non-Abelian gauge theories from a classical, geometric point of view, in analogy to Maxwell theory as a prototype, and culminates in an application to the U(2) theory relevant for electroweak interactions. The last chapter 6 gives a concise summary of semi-Riemannian geometry as the framework for the classical field theory of gravitation. The chapter concludes with a discussion of the Schwarzschild solution of Einstein's equations and the classical tests of general relativity (perihelion precession of Mercury, and light deflection by the sun)."

"Dibangun Sebuah lagrangian untuk menyatukan interaksi elektromagnetik dan dinamika fluida. Lagrangian ini memiliki simetri terhadap transformasi gauge lokal U(1)FD ⊗U(1)G dan G(n)FD ⊗G(n)G. Dari lagrangian ini kita akan menurunkan seluruh persamaan gerak untuk seluruh medan dan rapat energi sistem magnetofluida yang akan diaplikasikan untuk plasma quark-gluon."

"We impose the symmetry principles to elaborate the invariance of the Abelian and non- Abelian gauges and evaluate its implications to the laws of physics. The application of the symmetry principle into the field which undergoes a rotation in a phase space implies the exixtence of an Abelian gauge field Meanwhile, the application of symmetry principle to the dirac field as a doublet of SU (2)group implies the existence of a non - Abelian gauge field with structure constant satisfies the Lie group algebra."

"This excellent text covers a year's course in advanced theoretical electromagnetism, first introducing theory, then its application. Topics include vectors D and H inside matter, conservation laws for energy, momentum, invariance, form invariance, covariance in special relativity, and more."

"These lecture notes provide a tutorial review of non-Abelian discrete groups and show some applications to issues in physics where discrete symmetries constitute an important principle for model building in particle physics. While Abelian discrete symmetries are often imposed in order to control couplings for particle physics, in particular model building beyond the standard model - non-Abelian discrete symmetries have been applied to understand the three-generation flavor structure in particular. This text explicitly introduces and studies the group-theoretical aspects of many concrete groups and shows how to derive conjugacy classes, characters, representations, and tensor products for these groups (with a finite number) when algebraic relations are given, thereby enabling readers to apply this to other groups of interest."
