De Broglie’s matter wave (1924) Heisenberg’s matrix mechanics (1925) Schrodinger equation (1926) Klein-Gordon equation (1927) Pauli equation (1927) Dirac equation (1928)

A equation which describes de Broglie’s matter wave  very successful for most of the quantum mechanics  only particles with integer spin  non-relativistic quantum mechanics

Pauli equation: including spin ½ particles Fine structure: relativistic correction

A relativistic version of Schrodinger equation  simple combination of Schrodinger equation and special relativity  valid for spinless particles (only pion)  not fit with energy levels of hydrogen atom

Starting 4-vector invariance the same with Klein-Gordon equation

Satisfying 4-vector invariance Including spin states Possibility of negative energy First order differential equation
