摘要:Strong approximation with Brauer-Manin obstruction is defined by Colliot-Thélène and Xu to study the local-global principle for the integral points. When the Brauer group is finite, this can be view as a weak version of the relative Hardy-Littlewood property. Inspired by the asymptotic formula of integral points with coprime values or squarefree values in analytic number theory,  we consider their density in adelic space: the arithmetic purity and squarefree values of strong approximation. So in this talk, I will introduce those notions and outline our recent results for linear algebraic groups and homogeneous spaces.
