| Abstract: |
| Let $D$ be a positive integer with $D>1$, and let $p$ be a prime with $p\nmid D$. In this paper, by using properties and certain known results of diophantine equations with some elementary metholds, all positive integer solutions $(x,m,n)$ of the
equations $x^2=D^{2m}-D^mp^n+p^{2n}$ are determined. |
