Abstract

In this paper, we prove that the equation \(x^2-(p^{2k+2}+1)y^2=-p^{2l+1}\), \(l \in \{0,1,\dots ,k\}, k \ge 0\), where p is an odd prime number, is not solvable in positive integers x and y. By combining that result with other known results on the existence of Diophantine quadruples, we are able to prove results on the extensibility of some \(D(-1)\)-pairs to quadruples in the ring \({\mathbb {Z}}[\sqrt{-t}], t>0\).
