英文摘要: The recently proposed remarkable mechanism explaining the "stringy exclusion principle" on an anti-de Sitter space is shown to be another beautiful manifestation of the spacetime uncertainty principle in string theory as well as in M theory. Put in another way, once it is realized that the graviton of a given angular momentum is represented by a spherical brane, we deduce the maximal angular momentum directly from either the relation Deltat Deltax(2)>l(p)(3) in M theory or Deltat Deltax>alpha' in string theory. We also show that the result of McGreevy, Susskind, and Toumbas is similar to results on D2-branes in the SU(2) WZW model. Using the dual D2-brane representation of a membrane, we obtain the quantization condition for the size of the membrane.
