报告摘要：High dimensional space-time dimension and extra dimensional scale structure are the basic problems in high dimensional theory. With the discovery of GW170817 and its electromagnetic counterpart GRB 170817A, gravitational wave detection has gradually become one of the important means to test the existence of extra dimensions. Recently, the Princeton team, LIGO, and Virgo team have investigated the dimensionality of extra dimensions based on the graviton escape effect in higher-dimensional spacetime. In order to carry out complementarity research, we will introduce the principle of shortcut effect in high dimensional spacetime and propose a new scheme to limit spacetime dimension based on shortcut effect. In addition, we will discuss solutions for circumventing small-scale extra-dimensional structures, and illustrate their importance for future studies of higher-dimensional space-time gravitational wave signals.
