五、摘要

I shall start from several classical cohomological obstructions to local-principle of varieties, including Brauer-Manin, descent, \'etale-Brauer, homotopy type. Then we will recall known relations between them. After these, we generalizes obstructions to algebraic stacks and introduce some recent works (joint with Han Wu) in progress.
