This monograph gives a comprehensive presentation of the SL(2,C) Gauge Theory of Gravitation along with some recent developments in the problem of Conservation Laws in General Relativity. Emphasis is put on quadratic Lagrangians which yield the Einstein field equations, as compared with Hilbert's original linear Langrangian, thus gravitation follows the other Gauge Fields all of which are derived from nonlinear Lagrangians.Contents:IntroductionFundamentals of the SL(2,C) Gauge Theory of GravitationThe Quadratic LangrangiansEnergy Conservation Problem in General RelativitySL(2,C) Conservation Laws of GravitationNon-Rotating FramesReadership: Mathematical physicists and mathematicians.Key Features:Addresses analytically and comprehensively cardiac perfusion and pumping functions in terms of clinically determinable indicesDiscusses in depth the motivation and meaning of the derived and simulated resultsThe intrinsic beauty of the computational models and their solutions is emphasized and illustrated by unique full-color figures
