摘要 (Abstract): 

       This talk will discuss a new universal inequality about the inner structure of black holes. It will introduce a special cross-section inside black holes and conjectures a universal inequality: in a static (d+1)-dimensional asymptotically planar/spherical Schwarzschild-AdS spacetime of given energy E and AdS radius L, the ``size of cross-section'' inside black holes is bounded by 8pEL/(d-1). To support this conjecture, it gives the proofs for cases with spherical/planar symmetries and some special cases without planar/spherical symmetries. As one corollary, it shows that the complexity growth rate in complexity-volume conjecture satisfies the upper bound argued by quantum information theory. This makes a first step towards proving the conjecture that the vacuum black hole has fastest complexity growth in the systems of same energy. It also finds a similar bound for asymptotically flat black holes, which gives us an estimation on the largest interior volume of a large evaporating black hole.
