Most Popular comprehensive theory of gravitation, i. e. Einstein's general theory of relativity (GTR), actually moves away from the conventional understanding to "e; field"e; by identifying the field variable with the metric tensor of Riemannian space-time, thus making the theory completely geometric. As a result the GTR has proved to be devoid , in principal of conversation laws for matter and gravitational field when taken in conjunction. Many attempts even going back to the work of Einstein himself to introduce into the GTR a substitute for the energy momentum conversation law of matter and gravitational field taken in conjunction have all when closely scrutinized proved unsuccessful.This book provides various aspects of Group Theory, Gravitation and Elementary Particle Physics: An Introduction written in a simple and lucid style to help the reader grasp the information quickly and easily. The book contains 3 chapters and each chapter present update material sufficient to meet the students expectations from a basic textbook. The first chapter is on The Theory of Space-Time and Gravitation. Second chapter is on Inclusive Processes and Strong Interaction Dynamics. Third chapter is on Colored Quarks.
