Lecture Notes

Skewes Number

For my recent Online Math Notes on the Skewes Number, please click here. The Skewes Number is the least number for which the prime number theorem undercounts the number of primes. Two papers on this subject were published in July 2010: Chao-Plymen and Saouter-Demichel. The best upper bound for the Skewes Number is around exp(727.9513), a number with 316 digits, see Stefanie Zegowitz . For a popular lecture on this topic, please click here. The article of Stoll and Demichel is full of lively interest.
