Fig.4.11 - Graphical representation of delta function.Using the Delta Function in PDFs of Discrete and Mixed Random VariablesIn this section, we will use the delta function to extend the definition of the PDF to discrete and mixed random variables. Consider a discrete random variable XX with ...

In this paper, we deal with the historical origins of Fermi–Dirac statistics, focusing on the contribution by Enrico Fermi of 1926. We argue that thi
The support of the Dirac delta function in (3.13) is given by the zeros of the following function zw(ηxx, ηyy) ≡ w(ηxx) − w(ηyy) . (3.14) A crucial role is played by the point x˜ conjugate to x defined as x˜ ≡ a b . x (3.15) Notice that, if x ∈ A, ...
