Abstract

The problem of evaluating square-free values of polynomials is a classical problem that has attracted many authors, including Eetermann, Carlitz, Tolev and Zhou. Recently, for \(1\le x,y\le H\), Dimitrov established an asymptotic formula for the number of the square-free values attained by the polynomial \(f\left( x,y\right) =\left( x^2+y^2+1\right) \left( x^2+y^2+2\right) \). Motived by the work of Dimitrov, in this paper, we give an asymptotic formula for the consecutive square-free numbers \(x_1^2+\cdots +x_k^2+1\), \(x_1^2+\cdots +x_k^2+2\).
