  text: We establish the Hardy-Littlewood property (à la Borovoi-Rudnick) for Zariski
    open subsets in affine quadrics of the form q(x1,...,xn)=m, where q is a non-degenerate
    integral quadratic form in  n>3 variables and m is a non-zero integer. This gives
    asymptotic formulas for the density of integral points taking coprime polynomial
    values, which is a quantitative version of the arithmetic purity of strong approximation
    property off infinity for affine quadrics.
