E598 -- De insigni promotione scientiae numerorum
(English Translation of Title)
Summary:
Euler begins by noting Lagrange’s work on the divisors of numbers of the form Btt + Ctu + Duu and his
contribution to the "knowledge" or "science" of numbers. He includes the following problems:
- Find the divisors of pp + nqq.
- Transform frr + grs + hss, in which 4fh - gg = 4n, into a diferent form f’tt + g’tu+h’uu,
in which g’ < f’ and g’ < h’, and still maintaining the property 4f’h’ - g’g’ = 4n.
- Find all the prime divisors of numbers in the form pp + nqq, where p and q are relatively prime with
respect to n.
- Find all the prime divisors of numbers in the form pp - nqq, where p and q are relatively prime
with respect to n.
Then a big theorem answers everything.
According to the records, it was presented to the St.
Petersburg Academy on October 26, 1775.
