Is Dirac delta 0 linear?
The Dirac delta function 0 is a distribution. It is de ned by This is clearly linear. Some people (especially physicists and engineers) like to write when they mean 0[ ] to make it look more like (2.9), even though 0 is not a function. Let f : R ! R. Suppose f is di erentiable and f0 is integrable. Can we between Tf and Tf0?
When did Dirac introduce the delta function?
Dirac had introduced this function in the 1930′ s in his study of quantum mechanics as a useful tool. It was later studied in a general theory of distributions and found to be more than a simple tool used by physicists. The Dirac delta function, as any distribution, only makes sense under an integral.
