Diophantine Problems With Sums of Divisors

2014
Ayad i Luca su dokazali da ne postoji neparan prirodan broj n > 1 i dva pozitivna djelitelja d1, d2 od (n^2 + 1)/2 takvi da vrijedi d1 + d2 = n + 1. Dujella i Luca promatraju opcenitiji problem, gdje je linearni polinom n+1 koji je suma djelitelja d1 i d2 zamijenjen proizvoljnim linearnim polinomom dn + e, gdje su koeficijenti d i e cijeli brojevi i d >
