Motivated by the usual D2-D0 system, we consider a configuration composed of flat membrane and fuzzy sphere membrane in plane-wave matrix model, and investigate the interaction between them. The configuration is shown to lead to a non-trivial interaction potential, which indicates that the fuzzy sphere membrane really behaves like a graviton, giant graviton. Interestingly, the interaction is of r −3 type rather than r −5 type. We interpret it as the interaction incorporating the smearing effect due to the fact that the considered supersymmetric flat membrane should span and spin in four dimensional subspace of plane-wave geometry.Keywords: Penrose limit and pp-wave background, M(atrix) Theories ArXiv ePrint: 0812.4112
Durch Umsetzen von Allylisothiocyanat (I) mit N2H4‐ H2O im Molverhältnis 2:1 bei 80°C wird in hoher Ausb. Dalzin (II) erhalten, das als Reagens in der Metallkomplexchemie verwendet wird.
243ChemInform Abstract The title compounds (III) are synthesized from the thioxoquinazolone (I) and the alkylating agents (II). The S,N3-dialkylated product (IV) is formed with excess (II) in a more polar solvent.
