标题： Multidimensional Sigma-Model with Black Holes and p-Branes

摘要： 弦理论在具有p膜的多维结构弯曲背景中的玻色内容可以系统地描述为一个有效引力的σ模型，在较低维度（例如3+1）中具有额外的相互作用的标量和p膜场。 如果目标空间是局部对称的，可以找到具有相交p膜的解。 一些静态解是黑洞的p膜推广（包括标准的Reissner-Nordstr"om类），它们允许通过黑洞热性质的尺度特性预测高维p膜几何的可检测特征。 例如， 霍金温度T_H critically 依赖于p膜交叉拓扑。 显示英文摘要

摘要： The bosonic content of string theory in curved background of multidimensional structure with p-branes has a systematic geometrical description as an effective sigma-model of gravity in lower dimension (say 3+1) with additional interacting dilatonic and p-brane fields. If the target-space is locally symmetric, solutions with intersecting p-branes can be found. Some static solutions are p-brane generalizations of black holes (including the standard Reissner-Nordstr"om class), which allow the prediction of detectable features of the higher-dimensional p-brane geometry via scaling properties of black hole thermal properties. E.g. the Hawking temperature T_H depends critically on the p-brane intersection topology.
