This book introduces notation terminology and basic ideas of relativistic quantum theories.
The discussion proceeds systematically from the principle of relativity and postulates of
quantum logics to the construction of Poincaré invariant few-particle models of interaction and
scattering. It is the first of three volumes formulating a consistent relativistic quantum
theory of interacting charged particles. Contents Quantum logic Poincaré group Quantum
mechanics and relativity Observables Elementary particles Interaction Scattering Delta function
Groups and vector spaces Group of rotations Lie groups and Lie algebras Hilbert space Operators
Subspaces and projections Representations of groups and algebras Pseudo-orthogonal
representation of Lorentz group
