There are many representations of the delta function. Is there a place/reference that lists AND proves them? I am interested in proofs that would satisfy a physicist not a mathematician.
I wonder what you would consider a proof of a representation . A delta function is a something with certain well described properties. The word distributions comes to mind (out of the dust of ages). Showing that the representation exhibits such properties is just that: a showing.representations of the delta function. Is there a place/reference that lists AND proves them
What are the properties you refer to?I am actually comfortable with the delta function. It’s just that I am many years past grad school and was reading something (Intermediate Quantum Mechanics by Bethe) that piqued my interest in how to to show that these representations have the correct properties.
