| Summary: | This dissertation is devoted to the study of black hole and p-brane solutions and dualities in string theory. Strong evidence is presented that certain massive string states can be identified with extremal black holes. The degeneracy of these string states hints at a non-vanishing Beckenstein- Hawking entropy in contrast to the classical black hole analysis which reveals zero entropy. This discrepancy might be cured by quantum effects. In fact it is shown that taking loop corrections into account one finds that arbitrary p- branes in the near-extremal limit obey the entropy/temperature relationship of a massless ideal gas in p dimensions as expected from an open string D-brane description. For the special case p = 0 this result is consistent with a nonvanishing entropy of extremal black holes as indicated by string state counting. The four- dimensional extremal black holes also fit naturally into a string/string/string triality in four dimensions that relates the heterotic string compactified on a six-torus and the Type IIA and IIB strings compactified on K3 x T'. The implications of this interconnection between these different string theories are studied. |
