On the Diophantine equations $x^2-Dy^2=-1$ and $x^2-Dy^2=4$

In this paper, using only the Störmer theorem and its generalizations on Pell's equation and fundamental properties of Lehmer sequence and the associated Lehmer sequence, we discuss the Diophantine equations $x^2-Dy^2=-1$ and $x^2-Dy^2=4$. We obtain the relation between a positive integer solut...
