DIRAC DELTA FUNCTION IDENTITIES
Simplified production of 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 |
What is a simple derivation of delta function identities?
2. Simplified derivation of delta function identities. Let θ(x; ) refer to some (any nice) parameterized sequence of functions convergent to θ(x), and let a be a positive constant. While θ(ax; ) and θ(x; ) are distinct functions of x, they clearly become identical in the limit 0, and so also therefore do their derivatives (of all orders).
