摘要:
Various aspects of branes in the recently proposed matrix model for M-theory are discussed. A careful analysis of the supersymmetry algebra of the matrix model uncovers some central charges which can be activated only in the large N limit. We identify the states with non-zero charges as branes of different dimensions. (C) 1997 Elsevier Science B.V.
