On the number of pairs of positive integers $\mathbf{x, y \leq H}$ such that $\mathbf{x^2+y^2+1}$, $\mathbf{x^2+y^2+2}$ are square-free

Abstract: In the present paper we show that there exist infinitely many consecutive square-free numbers of the form $x^2+y2+1$, $x^2+y2+2$. We also give an asymptotic formula for the number of pairs of positive integers $x, y \leq H$ such that $x^2+y2+1$, $x^2+y2+2$ are square-free.
