Carl Severin Wigert

Carl Severin Wigert (1871–1941) was a Swedish mathematician who created Stieltjes–Wigert polynomials and worked on the divisor function, including correctly describing its maximal order of growth. Wigert proved that

\limsup _{n\to \infty }{\frac {\log d(n)}{\log n/\log \log n}}=\log 2.

gollark: The "and another member of your species" bit does have the interesting implication that you can't really call something alive or not if you just have one of it, then.

gollark: That is true, except I think some cells can't because of DNA damage or something.

gollark: I mean, individual animals can't reproduce on their own, except the weird ones which can.

gollark: Just general craziness.

gollark: They also said influenza wasn't contagious, which is especially crazy.
