The Dirac Equation - Warwick
This (and some others) problem drove Dirac to think about another equation of motion. His starting point was to try to factorise the energy momentum relation. In covariant formalism E 2 p m !pp m 2 (15) where p is the 4-momentum : (E;p x;p y;p z). Dirac tried to write p p m 2 = ( p + m)( p m) (16) where and range from 0 to 3. This notation ...

Notes 8: Fourier Transforms - Warwick
warwick.ac.ukThe Fourier transform is used to represent a function as a sum of constituent harmonics. It is a linear invertible transfor-mation between the time-domain representation of a function, which we shall denote by h(t), and the frequency domain representation which we shall denote by H(f). In one dimension, the Fourier transform pair consisting of ...
