In number theory, Skewes's number is the smallest natural number x {\displaystyle x} for which the prime-counting function π ( x ) {\displaystyle \pi (x)} exceeds the logarithmic integral function li ( x ) . {\displaystyle \operatorname {li} (x).} It is named for the South African mathematician Stanley Skewes who first computed an upper bound on its value.
