Travaux de Coates et Wiles sur la conjecture de Birch et Swinnerton-Dyer
In this paper, we demonstrate that 1 is the only integer that is both triangular and a repunit.
Our previous research was devoted to the problem of determining the primitive periods of the sequences where is a Tribonacci sequence defined by an arbitrary triple of integers. The solution to this problem was found for the case of powers of an arbitrary prime . In this paper, which could be seen as a completion of our preceding investigation, we find solution for the case of singular primes .
