M. Li et T. Yoneya, Short-distance space-time structure and black holes in string theory: A short review of the present status, CHAOS SOL F, 10(2-3), 1999, pp. 423-443
We briefly review the present status of string theory From the viewpoint of
its implications on the short-distance space-time structure and black hole
physics. Special emphases are given on two closely related issues in recen
t developments towards nonperturbative string theory, namely, the role of t
he space-time uncertainty relation as a qualitative but universal character
ization of the short-distance structure of string theory and the microscopi
c formulation of black-hole entropies. We will also suggest that the space-
time uncertainty relation can be an underlying principle for the holographi
c property of M theory, by showing that the space-time uncertainty relation
naturally explains the UV/IR relation used in a recent derivation of the h
olographic bound for D3 brane by Susskind and Witten. (C) 1999 Elsevier Sci
