报告摘要：This talk is devoted to the minimal time for the null-controllability of linear hyperbolic balance laws by means of one-sided boundary controls. It is known in some previous works that such a critical time can be sensitive to both internal and boundary coupling terms, especially when null and exact controllability are not equivalent. The necessary and sufficient conditions will be shown when the minimal time is invariant with respect to the internal couplings, no matter what the boundary coupling terms are. Some interesting counterexamples will also be discussed.
