What is the name of the limit that was named in honour of the person who was honoured by having the number that represents the number of protons named after him?
Eddington number In astrophysics, the Eddington number, "N", is the number of protons in the observable universe. The term honors the British astrophysicist Arthur Eddington, who in 1938 was the first to propose a value of "N" and to explain why this number might be important for physical cosmology and the foundations of physics.
Polylogarithm In mathematics, the polylogarithm (also known as Jonquière's function, for Alfred Jonquière) is a special function Li("z") of order "s" and argument "z". Only for special values of "s" does the polylogarithm reduce to an elementary function such as the natural logarithm or rational functions. In quantum statistics, the polylogarithm function appears as the closed form of integrals of the Fermi–Dirac distribution and the Bose–Einstein distribution, and is also known as the Fermi–Dirac integral or the Bose–Einstein integral. In quantum electrodynamics, polylogarithms of positive integer order arise in the calculation of processes represented by higher-order Feynman diagrams.
