含时全息积分几何

Holographic integral geometry with time dependence

Bartlomiej Czech, Yaithd D. Olivas, Zi-zhi Wang

摘要:

我们写下克罗夫顿公式-表达式,计算在渐近AdS $_3$几何空间的类空曲线的长度作为运动空间的积分-适用于当曲线和/或背景时空是时间依赖的。相对于它们的静态前身,含时Crofton公式显示了几个新的功能,其起源是局部零旋转对称的散装几何。在纯AdS $_3$中,零旋转是全局对称的,Crofton公式简化并成为零平面上的积分,零平面与体积曲线相交。

英文摘要:

We write down Crofton formulas--expressions that compute lengths of spacelike curves in asymptotically AdS$_3$ geometries as integrals over kinematic space--which apply when the curve and/or the background spacetime is time-dependent. Relative to their static predecessor, the time-dependent Crofton formulas display several new features, whose origin is the local null rotation symmetry of the bulk geometry. In pure AdS$_3$ where null rotations are global symmetries, the Crofton formulas simplify and become integrals over the null planes, which intersect the bulk curve.
