In 1961 Wirsing proved a theorem about the asymptotic means of non-negative multiplicative functions, and he was able to show, under certain conditions, that these are essentially determined by their values at the prime numbers (and not also by values at the higher prime exponents). In 1967 he

He gave in 1962 an elementary proof of a sharpened form of the prime-number theorem (with remainder). (In this context, "elementary" means "not using methods from

His results are presented, for example, in 657: 414:(1962). Elementary proofs of the prime number theorem were first published by Paul Erdős and 120: 62: 314: 163: 140: 692: 687: 422: 30:(28 June 1931 – 22 March 2022) was a German mathematician, specializing in number theory. 8: 583: 518: 343: 433:).
