WebEuler Function and Theorem. Euler's generalization of the Fermat's Little Theorem depends on a function which indeed was invented by Euler (1707-1783) but named by J. J. Sylvester (1814-1897) in 1883. I never saw an authoritative explanation for the name totient he has given the function. In Sylvestor's opinion mathematics is essentially about seeing … WebNov 30, 2024 · Euler’s Theorem: proof by modular arithmetic.
