11. This is simply a flat plane that contains a negative-valued Dirac delta function . 12. One approach to solving the Hamiltonian constraint starts with what is called the Dirac delta function . 13. This can be interpreted as a Dirac delta function that is created immediately after the pulse. 14. Furthermore, the Dirac delta function is not a function but it is a finite Borel measure. 15. Where \ delta is the Dirac delta function and H ( x ) the Heaviside step function. 16. For an infinite crystal, the diffracted pattern is concentrated in Dirac delta function like Bragg peaks. 17. :I think a case can be made that the Dirac delta function is one special case. 18. As a generalised function, the second derivative may be taken as two times the Dirac delta function . 19. This is often represented by the use of amplitude-variant Dirac delta functions at the harmonic frequencies. 20. Equality holds only for the two point Bernoulli distribution or the sum of two different Dirac delta functions .
