报告摘要：In this talk, I will introduce several stronger versions of sensitivity. Sensitivity is an opposite notion of equicontinuity, which is closely related to Chaos. I will show some dichotomy theorems of stronger versions of sensitivity under group actions. Besides, I will introduce n-tuplewise sensitivity and show some interesting results under Z-actions.
