标题： p-Brane Solutions in Diverse Dimensions

摘要： 一个通用的拉格朗日量，在任意时空维度中，描述了引力子、膨胀子和两个反对称张量之间的相互作用。 获得了一个各向同性的p膜解，由三个块组成，并依赖于拉格朗日量中的四个参数和两个任意调和函数。 对于拉格朗日量中特定的参数值，该解可以与之前已知的超弦理论解相识别。 显示英文摘要

摘要： A generic Lagrangian, in arbitrary spacetime dimension, describing the interaction of a graviton, a dilaton and two antisymmetric tensors is considered. An isotropic p-brane solution consisting of three blocks and depending on four parameters in the Lagrangian and two arbitrary harmonic functions is obtained. For specific values of parameters in the Lagrangian the solution may be identified with previously known superstring solutions.
