DIRAC DELTA FUNCTION IDENTITIES
DIRAC DELTA FUNCTION IDENTITIES Nicholas Wheeler Reed College Physics Department November 1997 Introduction To describe the smooth distribution of (say) a unit mass on the x-axis we introduce distribution function μ(x) with the understanding that μ(x) dx mass element dm in the neighborhood dx of the point x μ(x) dx = 1 |
Does a Dirac delta cancel itself?
Or alternatively you consider that the dirac delta is zero everywhere except at 0, and since we have an integral with a limit which approaches zero from above (positive) and then moves away heading in the positive direction, the integral must cancel itself. (Since there is a square.) This raises questions about the cubic order term.
How do you prove a Dirac delta?
The last line can be proven by substituting variables (twice) z = y2, y = x − ai. Or alternatively you consider that the dirac delta is zero everywhere except at 0, and since we have an integral with a limit which approaches zero from above (positive) and then moves away heading in the positive direction, the integral must cancel itself.
