These methods are very similar to ones applied to initial value problems for ordinary differential equations (ODEs) so we shall give a brief review of such methods in the next section.

Introductionies of elementary particles. Examples are the electron (e), the photon (.), the proton (p), the neutron (n), the pi-mesons or pions (.), the K-mesons (K), and the hyperons (Λ, Σ, etc.). Of these, the electron and the proton have been known for the longest time. At the time when the electron was disc
