Lorentz Covariance of the Dirac Equation,A proper relativistic theory has to be Lorentz covariant, i.e. its form has to be invariant under a transition from one inertial system to another one. To establish this we will first restate the essentials of . transformations and also refer to Chap. 14 for supporting group theoretical arguments.

Wave Equations for Particles with Arbitrary Spins,Here we want to outline briefly how to construct wave functions which describe particles with spin . = 1, 3/2, … out of solutions of the Dirac equation and also to study by what kind of wave equation they are generated.

Lorentz Invariance and Relativistic Symmetry Principles,We consider the four-dimensional space with coordinates .. (. = 0, 1, 2, 3), which — assuming the most general case — may be complex numbers.

Walter Greinerncluding vehicle wheel position, horizontal load, elasticity and thickness of the road layers on the crack tip parameters (i.e. stress intensity factors) are investigated using two-dimensional (2D) and three-dimensional (3D) FEM. For this purpose, a four-layer road structure including asphalt concre

Walter Greinerof the recent advances in the understanding of the fracture of glassy thermoplastics have been through the application of linear elastic fracture mechanics (LEFM, Section 3.2.2) which is applicable since their bulk deformation is approximately linear elastic and plastic deformation is concentrated i
