摘要: One basic philosophy in Diophantine Geometry is local-global principle (Hasse principle) for rational points and integral points. In this talk, I will focus on how to use linear  algebraic group to study the local-global principle for integral points and talk about:

(1) the descent obstruction and iterated descente obstruction;

(2) invariant Brauer subgroup and strong approximation of  homogeneous spaces;

(3) arithmetic purity of strong approximation for homogeneous spaces.
